PLEASE TRY THE FREE VERSION FIRST A fun way to learn the prime numbers less than 100 A set of 25 pixel picture puzzles Shade the squares that have prime numbers Identify Prime and Composite (non-prime) numbers 3 levels of difficulty Worksheets (A5/A4) + ANSWERS + blank grids Guidance/Instructions** Prior Knowledge Required Being able to identify some if not all the prime numbers less than 100 unless you use this as an activity for this purpose. This is an activity designed to make the learning of PRIME numbers much easier and I have been surprised, in the past, how successful it has been. Start with the PRACTICE question if needed. For this and ONE STAR PUZZLES the if you work through the grid, starting in the top left hand corner and work left to right and row by row the sequence of PRIME NUMBERS <100 appear IN ORDER. So find 2 and work through to 97 The sequence repeats (partially in some cases) up to the prime needed complete the puzzle Get them to do this methodically - this is how they pick up the sequence ( a printed sequence for them to have alongside may scaffold the initial process). TWO STAR - Same rules but generally a larger grid THREE STAR - Usually a larger grid but primes not in a particular order although some part of the prime sequence may occur. (Find a 2 and it may be next to a 3, then a 5, then a 7 etc etc) I have provided some blank grids for pupils to make up their own puzzles. Draw a picture by colouring in a small grid. Then working with a larger grid get them to write LIGHTLY SHADE their picture onto a big grid In each shaded square they then write a PRIME NUMBER (in sequence at first as in a one star puzzle) which gets them writing out the primes) FILL IN THE REST OF THE GRID WITH NON-PRIME which is an equally IMPORTANT TASK EITHER COPY THIS ONTO ANOTHER BLANK GRID or use COMPUTER and TABLE IN WORD, POWERPOINT or similar to produce a printable puzzle. I have used ADOBE’s InDesign to make this set of puzzles Please Comment/follow so if there are upgrades/changes you can be easily notified - Thank You

If you download please comment/follow so if the resource is updated I will be able to notify you. SEE MY OTHER DOMINO RELATED RESOURCES Virtually Identical to my set of Ladybird Domino 0-0 to 10-10 resource but with Extra dominoes so that a full set of 0-0 to 12-12 would cover THE TWELVE DAYS of CHRISTMAS. So 91 Dominoes altogether. Lots of opportunity to set differentiated tasks IDEAS FOR USE ALSO IN PDF You could even sing along to the domino you have or find ones that fit the song, as well as looking at all sorts of maths problems that could be weedled out of this topic. How many birds in total? How many men in total? How many women in total? Number patterns and sequences : 1 partridge on day one 1 partridge and 2 turtle doves on day 2 but thats 2 partridges and 2 turtle doves in total after 2 days … and 5 partridges ,8 turtle doves, 9 french hens, 8 calling birds and 5 gold rings after 5 days etc etc etc Perhaps could be used as a writing exercise in English. OR Just use as normal dominoes

For wordsearches this is quite a challenge. Hardly anyone has ever found all the words (even when they have taken home over an holiday period and arrived back saying it became a family activity) but a lot have said they enjoyed trying. In class some have wanted to do it on their own, some in a small group. But it has worked best as a table activity where they work together an pool their answers. I have also used it to just to find certain words from a small list of 10-20 that I have put on the board.

PLEASE NOTE THIS IS A PART FINISHED RESOURCE - but still usable WORKSHEETS and ANSWERS PROVIDED PRIME NUMBERS LESS THAN 100 - Via PRIME PIXEL PICTURES (set of 25) + more NOW AVAILABLE well a mixture of ideas to throw out there Basically you have a grid of numbers in this case between 1-100 Pupils identify and colour/shade in the prime numbers to produce a PIXEL PICTURE This resource is just an basic example where the primes come in order so they get to know the sequence Others are on bigger grids Different colours by condition set Prime mixed up I have found it surprisingly successful in getting the pupils to learn their prime numbers Also in this resource I have included a bit mash-up of various other areas of maths that could be brought in - PLEASE LET ME KNOW WHAT YOU THINK

Two Versions Number bond to 10 - addition & subtraction Finding Primes Both give same answer Colour squares dependent on condition I now have a set of 25 PRIME PIXEL PICTURES available to download - with various difficulties- worksheets and answers

Choose from A3, A2 and A1 versions of a poster showing all the prime number less than 10000. Will need to be printed and the tiles stuck together for A1 and A2 - instructions included The font size on the A3 version is only 12pt I always think that the white border around the edge to the final poster should be removed (for me, personally, it looks better and you don’t notice the “joins” as much). A2 should be 2 x A3 or 4 x A4 sheets to stick together A1 should be 4 x A3 or 8 x A4 sheets to stick together (depending on your printer settings) Please make a comment/follow so If there are any updates you can be notified.

I have only used this in an after-school club. The students appeared to like the challenge of drawing the best picture. To use it Adobe Flash Player will need to be installed on the computer (most have it automatically installed) and may work if opened in Internet Explorer Simple to use - Arrow Keys Change colour ,speed and size of pen by clicking with mouse. HARD to get a good picture ( as I suppose an Etch-A-Sketch is). It anyone wants to save and print one they’ve done you’ll have to ‘screen-shot’ it. ( but then you couldn’t keep an Etch-A-Sketch picture) Please comment if you find a use for it

**If you download and use this Free resource could you please comment/follow so I can use the information to develop addition resources ** A PDF file that had Ladybird Dominoes from 0-0 to 10-10 (66 dominoes over 11 pages) Normal set of dominoes 0-0 to 6-6 just print off pages 1 to 5 A very good activity for learning practicing number bonds to 10 (see image) or just used to play normal dominoes. Other possible ideas are outlined in the PDF. I have printed off a few sets on card and laminated them and are a big hit with the students Each domino is 6cmx12cm at 100% size (print off at lower % if smaller size is required)

For Classroom display or pupil books. in 5 sizes A1-A5 A5 black and white version for pupil/student books If you print off as a tile poster there is a file with some tips.

Did you every want that odd sheet of Specialist paper for a lesson and couldn’t find any? AND did you want/need any A3 size so you didn’t have to stick A4 sheets together? IN this collection you will find Black, Green, Blue, Red and Grey versions of the follow papers A4 and A3 GRAPH PAPER 2mm (grid line every 10 - major grid line every 20) 2mm ( major grid line every 10) 1mm (grid line every 10 - major grid line every 20) 1mm ( major grid line every 10) SQUARED 1cm 5mm 2mm 1mm ISOMETRIC 5mm 1cm 2cm SPOTTY 5mm (1pt spots) 1cm Triangluar (1pt spots) 1cm Triangluar (2pt spots) 2cm Triangluar (1pt spots) 2cm Triangluar (2pt spots) 1cm Squared (1pt spots) 1cm Squared (1pt spots) All are PDF files and sometime when viewing you might need to either zoom in or out to see the detail If printing the A3 version you will need to make sure it is sent to an A3 printer otherwise it will try to tile and you’ll end up with 4 sheets instead of 1. Any of the colour versions will print grey if printed in greyscale in various shades of grey depending on the colour. I have included a grey version that should print 50% black. IF there are any other PAPERS you want adding to this collection please make a comment and i’ll endeavour to add it to the collect as soon as possible. I hope there are useful!

First an apology to every one who has downloaded it so far this so far. I accidently uploaded a development version of this resource that lack the functionality of of working with the tabs to change between CUSTOMISE QUESTION and ANSWERS. Everything should be OK now see the cover image on what you should be seeing. I usually use this resource at a starter or a settler activity with a given time limit (say 10 mins). I give advice about doing as many as possibly and in whichever order the students want. Afterward we have discussions about which they find the easiest or can do the quickest. Usually addition comes out the easiest until I suggest that if you know your tables that the multiplications are the easiest to do and probably the quickest as they don’t need working out. They get to realise that if they really know their tables that the divisions are quicker as they’re usually a single digit number to write as the answer. In my mark book I record how many get correct out of how many they do and a time if they complete them all before the given time. Most of the students really like doing this challenge. Improving their time/score is appears to motivate them. I have had quite a few students ask for sheets so they can practice at home. Use the TABS on the spreadsheet to set the difficulty by changing the MAX and MIN values for each mathematical operation, See the questions(recalculate if necessary ) and the answers for that set of questions. It may be a good idea to PRINT SCREEN a set of answers if you intend to put the answer in a PowerPoint. I usually print a few sets of answers off per table so they can mark their own. Sometimes I read them out. If you cut the answer sheet into 4 strips, these strips can be placed/matched up against each column of students answer sheet and this is really easy for them to mark. Using this technique I have marked a full class of sheets in about 5 mins or so. Another way to use this resource them would be to do them one/two columns/operations at a time and cut the time allowed.

If you download please comment/follow so if the resource is updated I will be able to notify you. this resource is PART OF a SET that I have split into single items SEE MY OTHER DOMINO RELATED RESOURCES INCLUDED a set of dominoes with the MULTIPLICATION Symbol FOR PRINTABLE SETS OF DOMINOES with ADDITION, SUBTRACTION symbols on the dominoes or just PLAIN - SEE MY OTHER UPLOADS There is a worksheet for INEQUALITES ( <,> and =) for NUMBER WORK 0-0 to 12-12 approx (5cm x 10cm at 100%) I printed these on CARD and laminated them, other sets were printed on different coloured card Remember to just print Page 1 or yo will print the example/instructions on page 2

I have used this with all year groups / all abilities as both a starter activity and a lesson resource when covering this topic. It can be used by student or staff on a computer by hovering/rolling/clicking a specific number They can come to the interactive whiteboard and touch one of the numbers to give them the prime factor/index notation for that number. It can be used to check sets of questions from worksheets or as part of a prime factor bingo game. It needs Adobe Flash Player installed on the computer it is being used on. ( Most computers do have this) If anyone can think of other uses please make a comment. *** Apologies to the first few people who downloaded this resource as I mistakenly uploaded the incorrect version- should be OK now) There was a problem with 34 and 78

You can simulate the throwing of up to 3 dice on a whiteboard for classroom activities. You will need Adobe Flash Player installed on you computer. (they usually do have it installed as standard) Now 2 files that basically do the same thing (the update file has an slightly different menu system) Please check out my other upload that simulates dice throwing and so you can look at expected outcomes and experimental outcomes.

In this EXCEL FILE - Simulate the throwing of 1,10,100,1000,10000 or 100000 dice at a time with the click of a button. A bar graph and pie chart are updated with each click. Hopefully a useful tool for demonstrating that experimental probabilities differ from expected probability but as you increase the frequency of the experiment that they get closer to the expected. the Excel worksheet does use MACROS to make the buttons work and you may be asked to enable them. Some versions of Excel don’t allow this so it will be a case just trying it (sorry if it doesn’t work for you)

A program (in Adobe Flash) that displays the factors/factors pairs for all the numbers 1-100 Really useful factor related activities and for checking worksheet answers. Lots to discus with the students. Same colour coding as my FREE Factor Banner/Poster which, at the moment, is my most popular download. Should work on the touch of an interactive whiteboard . Flash should work on most computers/laptops and I have had this working through Internet Explorer. If you are able to make a comment/follow I would be grateful as it lets me notify you if there is any changes/upgrades to it.
