Using Movement to Get Ready For Multiplication Example 1: Teacher asks 10 children to join the game. She explains that they run with the music and listen to the instruction when it stops. Music Stops Get together in 2's. How many groups? Solution : 2 + 2 + 2 + 2 + 2 = 10 The Children count 5 . So 5 groups of 2 = 10 Music Starts After some seconds Music Stops Get together in 5's. How many groups? Solution : As the number of children are 10 so 2 groups of 5. 5 + 5 = 10 The Children count 2 . So 2 groups of 5 = 10 _____________________________________________________________________ Example 2 :  Each contains 5 leaves and there are 4 groups. 5 + 5 + 5 + 5 = 20 In short 4 times 5 = 4 x 5 = 20 _____________________________________________________________________ Example : 3  Each necklace contains 5 beads and there are 2 groups. 5 + 5 = 10 In short 2 times 5 = 2 x 5 = 10 __________________________________________________________________ Q.1 Write the number of groups : • 6 + 6 ----> 2 groups of 6 ( 1st one is done for you) • 3 + 3 + 3 • 4 + 4 + 4 + 4 • 10 + 10 • 9 + 9 + 9 + 9 + 9 Q.2 Write the following using multiplication. • 7 + 7 + 7 • 11 + 11 + 11 • 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 • 15 + 15 • 13 + 13 + 13 2nd Grade Math Home Page Covid-19 has affected physical interactions between people.
