Multiply as 'sets of' and divide as 'how many sets - Teaching Presentation - Year 1

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

• Understand multiplication as repeated addition.

• Use multiplication sentences to describe a practical problem.
• Begin to make links to division (how many sets of).
• Solving multiplication and division problems.

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
Sit children in a circle and place four bags of 5 buttons in the middle. How many buttons in total? Model counting in 5s: 5, 10, 15, 20. Write on the board: 4 × 5 = 20. Repeat with three bags of 5 buttons, six bags of 5 buttons and then eight bags of 2 counting bears.

Day 2 Teaching
Build three towers of 10 cubes. How many cubes in total? Count in 10s to establish 30. Then record on the board: 3 × 10 = 30. Repeat to find five towers of 10 cubes. Then show 40 cubes on the floor and ask how many towers of 10 cubes can children make from these.

Day 3 Teaching
I have five 2p coins in my purse. How much money do I have altogether? Discuss, then count in 2s to 10p. Record on the board: 5 x 2p = 10p. Repeat for eight 2p coins in the purse. I have 8p in my purse. All of the coins are 2p coins. How many 2p coins are there? On a 0-50p penny line, circle groups of 2p up to 8p. There are four groups of 2 in 8p, so I must have four 2p coins! Repeat with other problems like this.

This teaching is part of Hamilton’s Year 1 Multiplcation, Division and Fractions 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.
