Count 2s, 3s, 5s, 10s; multiples of 2, 5, 10 - Teaching Presentation - Year 2

This presentation provides two days of teaching that cover the objectives:

• Count in steps of 2s, 3s and 5s.
• Count in 3s, making links to multiplication.
• Identify multiples of 3.

It includes starter activities, whole class teaching, group activities, practice sheets and mastery questions. It can be used on a variety of interactive whiteboards.

Day 1 Teaching
Count in 2s to 50, marking the 2s on Number Grid ITP. Mark 2s from 52 to 100 using the (stripes) pattern. Repeat to count in 5s; spot the pattern. Note multiples of 2 and 5 (10s). Count on in 3s, noting which numbers which are also multiples of 2 (6x table) and 5 (15, 30, 45). Which is a multiple of 2, 3 and 5? (30)

Day 2 Teaching
Use ITP Number Grid to highlight the count in 3s. We are counting on in 3s, adding 3 each time, so 3 + 3 is 6, 6 + 3 is 9, 9 + 3 is 12. These are multiples of 3. Note the pattern. Add the digits of each multiple of 3 in turn and show that these always add to 3 or 6 or 9 – our mathematical test to check if any number is a multiple of 3: finding the digit sum of the number. Try this for some big numbers, e.g. 123, 412, 339 and 450.

This teaching is part of Hamilton’s Year 2 Number, Fractions and Money block. Each Hamilton maths block contains a complete set of planning and resources to teach a term’s worth of objectives for one of the National Curriculum for England’s maths areas.
