Math practice · Week 13 · Thursday
I can solve a two-step adding story.
Look: Ana has 14 red beads and 18 blue beads. Then she gets 20 more.
- Step 1: 14 + 18 = 32.
- Step 2: 32 + 20 = 52. Ana has 52 beads.
- The answer to step 1 is a part in step 2.
Draw a bar for each step. Write two equations. Number them 1 and 2.
- A class picked up 26 cans on Monday and 17 cans on Tuesday. On Wednesday they picked up 21 more. How many cans in all?Answer: 1) 26 + 17 = 43. 2) 43 + 21 = 64. 64 cans.
- Jamal has 15 toy trucks. He gets 8 for his birthday and 13 from his uncle. How many trucks does he have now?Answer: 1) 15 + 8 = 23. 2) 23 + 13 = 36. 36 trucks.
- A garden has 32 red flowers and 29 yellow flowers. Then Mei plants 16 white flowers. How many flowers now?Answer: 1) 32 + 29 = 61. 2) 61 + 16 = 77. 77 flowers.
Challenge
- In problem 1, what answer would you get if you forgot step 2?Answer: 43 cans. That is too few, because the Wednesday cans are missing.
