lesson
Make regular jumps
1 · Learn
Multiples of six are 0, 6, 12, 18 and so on. A regular jump size helps predict later numbers. Twenty-five is a quarter of one hundred, so four jumps of 25 make 100.
Counting in thousands changes the amount by 1,000 each time, including when a number has hundreds, tens and ones as well.
2 · Worked example
Starting at 2,450, one thousand more is 3,450 and one thousand less is 1,450.
3 · Your turn
Continue 54, 63, __, __. Find 1,000 less than 5,072.
Check your answer
72, 81; 4,072.
4 · Apply your learning
Count forwards and backwards in 6s, 7s, 9s, 25s and 1,000s. Say the step and starting point before each sequence.
Adult guidance and safety
Use practical or drawn representations and explain the method. Check units and labels. A correct answer to one example is not evidence of secure fluency; revisit with varied numbers and feedback.
