- The image displays five different addition strategies: Number Line, Partitioning, Standard Columns, and two others partially visible.
- For the Number Line strategy, 3 + 9 is solved by starting at 3 and making 9 hops to reach 12; similarly, 23 + 14 starts at 23, partitions 14 into 10 and 4, makes a hop of 10 to 33, then a hop of 4 to 37.
- The Partitioning strategy breaks numbers into tens and ones: 76 becomes 70 + 6, and adding 12 (10 + 2) gives 80 + 8 = 88; another example shows 24 + 104 broken into 20 + 4 and 100 + 4, resulting in 120 + 8 = 128.
- The Standard Columns method aligns digits by place value: 54 + 68 adds 4 + 8 = 12 (write 2, carry 1), then 5 + 6 + 1 = 12, giving 122; 276 + 459 adds 6 + 9 = 15 (write 5, carry 1), 7 + 5 + 1 = 13 (write 3, carry 1), 2 + 4 + 1 = 7, resulting in 735.
- The other two strategies are partially cut off but appear to involve similar place-value or step-by-step addition methods.
Parent Tip: Review the logic above to help your child master the concept of addition strategies.
