Solve divisions as inverse of multiplication - Teaching Presentation - Year 2

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

• Write divisions to match arrays and divide using beaded lines.
• Solving word problems using multiplication or division.

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
Show an array of 3 rows of 5 counters. Describe the division shown. Record 15 ÷ 5 = 3. 15 has 3 lots of 5 in it. Rotate the array so it has 5 rows of 3 counters. What number sentence can we write? 15 ÷ 3 = 5. 15 has 5 lots of 3 in it. Show on a beaded line. Then use a beaded line to find 18 ÷ 3.

Day 2 Teaching
Remind children of previous word problems. Those were all multiplication problems. Today we will decide whether to multiply or divide to solve a word problem. Display the first two questions on the sheet and assist children in deciding whether to multiply or divide.

This teaching is part of Hamilton’s Year 2 Calculations 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.
