Teaching Presentation: Division using efficient chunking (Year 4 Multiplication and Division)

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

• Division using efficient chunking

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
Write 96 ÷ 6 and read it, reminding children that it asks us how many 6s in 96? Draw an empty number line and model finding 10 lots of 6 and then 6 lots (see download).
Point out that 10 + 6 is 16 so we know there are 16 lots of 6 in 96. Ask children to show 78 ÷ 6 and 72 ÷ 4.

Day 2 Teaching
Show the posters made yesterday. Ask children to share how we use a number line to help us divide. First, we find 10 times the divisor, then we work out how many more lots we need. Model 102 ÷ 6 as 10 × 6 and 7 × 6 on a number line. Repeat for 72 ÷ 4 and 54 ÷ 3.

This teaching is part of Hamilton’s Year 4 Multiplication and Division 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.
