Math practice · Week 14 · Thursday
I can solve a two-step take-away story.
Look: A train had 70 riders. 24 got off. Then 18 more got off.
- Step 1: 70 − 24 = 46.
- Step 2: 46 − 18 = 28. There are 28 riders left.
- Check another way: 24 + 18 = 42. 70 − 42 = 28.
Draw a bar for each step. Write two numbered equations.
- Ella had 72 beads. She used 25 for a bracelet and 18 for a ring. How many beads are left?Answer: 1) 72 − 25 = 47. 2) 47 − 18 = 29. 29 beads.
- A bakery made 90 rolls. It sold 36 in the morning and 27 after lunch. How many rolls are left?Answer: 1) 90 − 36 = 54. 2) 54 − 27 = 27. 27 rolls.
- Ravi has 45 stickers. Jo has 18 fewer than Ravi. Then Jo gives 9 away. How many stickers does Jo have now?Answer: 1) 45 − 18 = 27. 2) 27 − 9 = 18. 18 stickers.
Challenge
- Solve problem 1 another way. Add the two parts she used first.Answer: 25 + 18 = 43. 72 − 43 = 29.
