Count in equal steps
1 · Learn
Counting in fours gives 0, 4, 8, 12, 16. Counting in eights gives 0, 8, 16, 24, 32. Every second multiple of four is a multiple of eight.
Counting in fifties gives 0, 50, 100, 150. Counting in hundreds gives 0, 100, 200, 300. A constant step makes a predictable pattern.
2 · Worked example
From 350, two fifty-steps forward give 400 then 450.
3 · Your turn
Continue: 24, 32, __, __. Count backwards in fifties from 300 for three steps.
Check your answer
40, 48. The backward steps are 250, 200, 150.
4 · Apply your learning
Use number cards to build and check one forward and one backward sequence.
Adult guidance and safety
Use objects or a drawn model before relying on a rule. Explain each step, check the units and revisit with varied examples. An adult can read the instructions without supplying the answer.
