Repeated addition problems
Lerato has done the first one for you.
Gogo bought 3 packets of sweets. Each packet has 2 sweets. How many sweets are there altogether?
There are 4 trees in the garden. Each tree has 2 apples. How many apples are there altogether?
There are 3 children on the bench. Each child has 3 sweets. How many sweets are there altogether?

There are 6 monkeys on a branch. Each monkey has 2 bananas. How many bananas are there altogether?
Check that learners can remember the important steps to solving word problems. Write these steps on the board. Practical example: have 4 learners stand up. Each learner has 2 eyes. How many eyes do they have altogether? (2 + 2+ 2+ 2 = 8. Another way to say this is 4 lots of 2 or 4 x 2 = 8). Repeated addition is the same as multiplication. Have 2 learners stand up. Each child has 10 f ingers. How many f ingers do they have? (10 + 10, or 2 lots of 10 or 2 x 10) .

Lerato loves addition. She wants to do some repeated addition sums. Help her find the answers. Remember the steps for solving the word problems.
Repeated addition
3 monkeys picked bananas off the tree. Each monkey picked 3 bananas. How many bananas did they pick altogether?
Mrs. Maneli planted 5 rows of pumpkins. Each row had 2 pumpkins. How many pumpkins did she plant altogether?
Lerato went to pick some apples. There were 2 trees. Each tree had 5 apples. She picked all the apples. How many apples did she pick altogether?
Remind learners of the steps for solving word problems. Explain to learners that repeated addition is the beginning of multiplication.
