#### Combined Transformations Puzzle Worksheet

(0)
An opportunity for students to practice the transformations skills required at foundation and higher tier level. Complete each transformation to solve the puzzle. Click here for the answer sheet showing the completed puzzle. I’d suggest giving students two copies of the worksheet- one for working and one for their final solution.

#### Finding Error Intervals (Bounds) + Answers

(0)
Suitable for higher (or more able foundation) level GCSE students. The main task covers writing error intervals for numbers rounded to any place value or significant figure. The task includes three different activities - so plenty of practice without the repetition. The follow up task introduces using bounds in calculations. As with all my activities - answer sheets are included. I normally leave a copy at the back of the room for students to mark from as and when they need.

#### Bounds (Error Intervals) - The Towering Inferno

(0)
A complete lesson designed to give students the opportunity to practice the use of bounds (error intervals) in a ‘real’ life context - The Towering Inferno. The lesson slides include a link to a clip of the film to show to students, as well as the solution to the problem. The task cards contain the problem and all the information required (as well as a few additional facts).

#### Mental Maths Daily Warm Up - Free Sample

(1)
What’s the best way to improve your students’ mental maths skills? … Practice! Use these sets of ten questions every day to improve key mental maths skills. Read the ten questions to your class, followed by the answers. Students mark their own or each others - the whole process is done within minutes. “We start every maths lesson with these ten quick questions, not only is this brilliant practice, but it acts as a great settler - silent students within seconds of the lesson starting!” This sample includes six sets of questions at the ‘easier’ and ‘trickier’ level. A free tracker grid is also included (trimmed, fits nicely stuck in the back cover of an exercise book). Complete sets for the whole year available here: easier and trickier At the ‘easier’ level, the skills covered are: Timestables (up to 10 x 10) Multipliying/dividing by 10 and 100 Number bonds to 100 Adding/subtracting with negatives Using the order of operations Timestables (up to 15 x 15) At the ‘trickier’ level, the skills covered are: Timestables (up to 10 x 10) Multipliying/dividing by 10 and 100 Number bonds to 100 Percentages/fractions of an amount Common powers and roots Adding/subtracting with negatives Using the order of operations Timestables (up to 15 x 15)

#### Real Area (+ Written Multiplication)

(0)
An exciting consolidation to any series of lessons on area (although this could easily be used as an introduction lesson too). In brief: Students are asked to order a series of photos in ascending order of area, before making estimations of the distances involved and then reordering. Finally, using the real values, calculate the areas and compare the actual order to their guesses. Included: Notebook lesson file Photo cards Full set of worksheets Skills covered include: Estimation of lengths from real world examples (using clues from the photo cards) Calculating the area of rectangles and triangles Using written multiplication methods I have used successfully with KS3 or foundation level KS4. This can be easily differentiated by removing some of the distances given in the tables in task one, or including additional photos (such as the circular O2 arena). I have used one of the buildings in our school, I’d recommend swapping that photo for a landmark local to your school.
