1 - Getting Started ~4 mins

Here is a number on the board: 3,450. I want you to picture it changing.

What is 100 more than 3,450? And here is the interesting part: which single digit changed to get there?

👇 Mark your steps as done as you complete them.

+5 XP

2 - Watch and Notice ~9 mins

Here are four jump examples. For each one, decide where the jump lands and keep an eye on which digits change. Sometimes it is more than one.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~8 mins

Today we work through these together on the number line: 10 more than 4,180, then 10 less than 3,506, then 100 more than 2,970, then 1000 more than 7,300. We will name the jump before we draw it, and we will spot every time a column rolls over.

Try It Together: jump 10s, 100s and 1000s

4 - Write More and Less in Your Copy ~3 mins

COPYBOOK MOMENT

In your maths copy, start from the number your teacher gives you. Write the number that is 1 more, 10 more, 100 more and 1000 more, one under the other.

Then do the same going the other way: write 1 less, 10 less, 100 less and 1000 less. Watch for any place where a column rolls over.

+10 XP

5 - Class Challenge ~7 mins

Today we reach these targets by adding one jump each time: 100 more than 3,950, then 1000 more than 8,200, then 10 less than 4,605, then 100 less than 7,040. Predict where each one lands before we check, and watch out for a column rolling over.

Class Challenge: reach the target
