1 - Getting Started ~3 mins
Look at the steps up to the school door. Each step is one higher than the last.
If we built our own staircase from cubes, what would step 5 look like?
2 - Watch and Notice ~8 mins
Two staircases on the board. For each one, watch how much it grows at every step: that amount is the growing rule.
Now a different staircase. How much does this one grow at every step?
3 - Try It Together ~9 mins
Today we build the next step of the 1, 2, 3 staircase. What does step 4 look like? Say the growing rule before the new tower lands.
Build the next step
4 - Draw the Staircase in Your Copy ~5 mins
In your maths copy, draw a staircase of towers with 1, 2, 3 and 4 squares.
