Planning and Activities
Day 1
Use a counting stick to model counting on and back in steps of 100, then steps of 50. Begin with counting in these steps from zero; then move to counting from other numbers, e.g. 78, 4, 23.
Further Teaching with Y4
Count on in 25s, identifying and reasoning about repeating patterns in 10s and 1s digits.
Group Activities: T with Y4
Y3 Use the in-depth problem-solving investigation ‘Dog Chews’ as today’s group activity.
Or use these activities:
-- Play ‘Ping Pong’, alternating between counting in 100s and 50s to 1000. Other children play ‘Jump 50, Jump 100’, counting on a given number of 100s or 50s.
Y4 -- Count back in 25s to find the smallest positive number that started a sequence of counting in 25s.
Day 2
Identify a general ‘rule’ to describe the steps in a sequence, e.g. add/subtract 4, double; write subsequent numbers in the sequence.
Further Teaching with Y4
Introduce, then begin to read and write Roman numerals.
Group Activities: T with Y3
Y3 -- Play a sequences card game, challenging a partner to identify the rule for a sequence and to write the next three numbers.
Y4 Use the in-depth problem-solving investigation ‘Roman numeral teaser’ as today’s group activity.
Or use this activity:
-- Investigate writing times tables using Roman numerals. Identify and reason about any patterns.
