Class 8 Maths · A Square and a Cube
Sprint 2 of 7: Squares, Odd Numbers and Triangular Numbers
Inside this sprint
- 1Explain
- 2Try it (on the right)
- 3Explain
- 4Fill in
- 5Order
- 6Try it (on the right)
Add the odd numbers
1
= 1 = 1 × 1
One square. Now wrap it.
Guess the next total
Add the odd numbers in order and the total is always a square. Here you can see why.
Built on how memory works. Not on how much we can fit in.
Small.
One concept per sprint, because memory takes in only a few new things at once.
Sweller · Mayer
Seen.
Every idea is drawn. Words and pictures together leave two memories, not one.
Paivio · Standing
Done.
You fill in, match, sort and write. Doing beats listening to a lecture.
Freeman et al., 2014
Checked.
Every sprint ends in a check, so you know what to go back to.
Roediger & Karpicke, 2006
