Working out the formula for triangular numbers

(12)
Top set Y6. Showing how to work out the formula for the triangular numbers from a simple visual stimulus. All of the set could explain in words the formula and most could write it down. They remembered it afterwards too!! Feel free to alter the initial slides for you class.

TU x U, HTU x U and HTU x TU. Enable macros to allow the sheet to generate new calculations. One note is that it could generate duplicates calculations as I haven't found a way to avoid this yet (not tried too hard) but just hit the button again to generate another sheet.

Co-ordinates Treasure Map

(13)
A treasure map using the 4 quadrants. Using the initial co-ordinate clue the children find the first letter (O). This letter then gives them the clue to the next co-ordinate and so on until the arrive at the final letter (P). Used it on my lower ability Y5 set with a lot of success. The ones who could, managed it very quickly and could then go on to design their own, and it was very easy to pick out the ones who couldn't and give them assistance. They all managed it eventually.

Character, setting and dilema

Hit the smiley in the middle and a new character, setting and dilemma are chosen automatically (with pictures). Sorry it is a but rough but my set enjoyed hitting the smiley and the quick 10 minute writing task, particularly the boys. It is possible to change the character, setting and dilemma they are in the hidden rows from 2 to 17, you might not like some of the syntax, but the images are a but more difficult as the are hidden.

Mode, Median and mean

(1)
Generates a list of 25 random numbers less than 100, then sorts them numerically (leaving original order for comparison) automatically calculates mode, median and mean, with a graph of the three results. Make sure you enable macros then press the top button to set up the needed addins and to undo them when finished press the bottom button. (The buttons just ensure that the iterations are set correctly). No I didn't know what that meant until I made this spread sheet either :)
