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 Covid19 has affected physical interactions between people.
