2 - Watch and Notice ~9 mins

Here are three sequences. Watch how the numbers change each time and see if you can work out the rule for each one: 3, 6, 9, 12 then 50, 45, 40, 35 then 2, 4, 8, 16.

👇 Mark your steps as done as you complete them.

3 - Try It Together ~8 mins

Today we work through these sequences together on the number line: 6, 12, 18 then 100, 90, 80 then 1, 3, 5, 7. For each one we hop the marker to the next number and say the rule out loud before we check it.

Hop to the next number

Today we continue these sequences together: 5, 10, 15, 20 then 90, 80, 70, 60 then 1, 3, 5, 7 then 1, 2, 4, 8. We work out the next number, place it on the line, and check it.
