Rearrange the parts of a sum to form new number sentences with this worksheet.
Rearranging Parts Strategy
The rearranging parts strategy can be a useful tool for helping students in the early years understand basic addition and subtraction. By breaking down a problem into smaller parts and rearranging those parts differently, students can better understand the problem and develop their problem-solving skills.
This worksheet displays a two boxes of dots representing a number sentence. Students determine the initial number sentence by counting the dots in each box (the parts) and then determining the total (the whole). Once they have the total, they rearrange the parts in a different way to create a new number sentence with the same total.to make ten.
An alternate version with the totals already filled in is provided to assist students who may have trouble understanding the concept.
Tips for Differentiation + Scaffolding
In addition to individual student work time, use this worksheet as a:
- specific rotation or guided group
- lesson exit ticket
- fast finisher activity
- homework assignment
- whole-class review (via smartboard).
Expand this activity for students who are more capable by asking them to choose the easiest combination of numbers to add.
Encourage students who need additional help to use concrete materials such as counters to match the number of dots used in each question and then rearrange and record their answer.
