Multiplication as Repeated Addition Fun
Year 1 Mathematics Learning to multiply by adding groups
What Are Groups?
Groups are sets of the same number of things Each group has the same amount We can count how many groups we have We can count what's in each group
Let's Count in Twos!
Stand up and clap with me 2, 4, 6, 8, 10... Use your fingers to help count Can you hop in twos?
Groups Become Addition
3 groups of 2 apples 2 + 2 + 2 = ? Let's count: 2, 4, 6 We have 6 apples altogether!
Multiplication Magic
Multiplication is just repeated addition! 3 times 2 means 3 groups of 2 3 × 2 = 6
Make Your Own Groups
Work with a partner Use counters to make groups of 2 Count how many groups you made Write the addition and multiplication
Let's Practice Together
{"left":"4 groups of 2 cars\n2 + 2 + 2 + 2 = 8","right":"5 groups of 2 stars\n2 + 2 + 2 + 2 + 2 = 10"}
What Did We Learn Today?
