Numicon Shape Addition within 50 worksheet with colorful shapes for engaging math practice.

To solve these problems, we need to count the blue dots (which represent tens) and the colored dots (which represent ones) for each shape, add them together, and then find the total sum.

Here is the step-by-step solution for each row on the worksheet:

Row 1:
* Left Shape: 3 columns of 10 blue dots = 30. Plus 4 green dots = 34.
* Right Shape: 1 column of 10 blue dots = 10. Plus 5 red dots = 15.
* Addition: $34 + 15 = 49$

Row 2:
* Left Shape: 3 columns of 10 blue dots = 30. Plus 2 green dots = 32.
* Right Shape: 2 columns of 10 blue dots = 20. Plus 6 green dots = 26.
* Addition: $32 + 26 = 58$ *(Note: This goes over 50)*

Row 3:
* Left Shape: 2 columns of 10 blue dots = 20. Plus 3 cyan dots = 23.
* Right Shape: 3 columns of 10 blue dots = 30. Plus 4 yellow dots = 34.
* Addition: $23 + 34 = 57$ *(Note: This goes over 50)*

Row 4:
* Left Shape: 1 column of 10 blue dots = 10.
* Right Shape: 3 columns of 10 blue dots = 30.
* Addition: $10 + 30 = 40$

Row 5:
* Left Shape: 4 columns of 10 blue dots = 40. Plus 6 cyan dots = 46.
* Right Shape: 1 column of 10 blue dots = 10. Plus 4 red dots = 14.
* Addition: $46 + 14 = 60$

Row 6:
* Left Shape: 3 columns of 10 blue dots = 30. Plus 5 cyan dots = 35.
* Right Shape: 2 columns of 10 blue dots = 20. Plus 4 pink dots = 24.
* Addition: $35 + 24 = 59$

Row 7:
* Left Shape: 2 columns of 10 blue dots = 20. Plus 4 red dots = 24.
* Right Shape: 2 columns of 10 blue dots = 20. Plus 5 cyan dots = 25.
* Addition: $24 + 25 = 49$

Row 8:
* Left Shape: 4 columns of 10 blue dots = 40. Plus 5 purple dots = 45.
* Right Shape: 1 column of 10 blue dots = 10. Plus 3 orange dots = 13.
* Addition: $45 + 13 = 58$

Row 9:
* Left Shape: 4 columns of 10 blue dots = 40. Plus 5 cyan dots = 45.
* Right Shape: 2 columns of 10 blue dots = 20. Plus 4 cyan dots = 24.
* Addition: $45 + 24 = 69$

Row 10:
* Left Shape: 2 columns of 10 blue dots = 20.
* Right Shape: 2 columns of 10 blue dots = 20. Plus 5 green dots = 25.
* Addition: $20 + 25 = 45$

Row 11:
* Left Shape: 2 columns of 10 blue dots = 20. Plus 4 red dots = 24.
* Right Shape: 2 columns of 10 blue dots = 20. Plus 5 green dots = 25.
* Addition: $24 + 25 = 49$

Row 12:
* Left Shape: 3 columns of 10 blue dots = 30.
* Right Shape: 3 columns of 10 blue dots = 30.
* Addition: $30 + 30 = 60$

Row 13:
* Left Shape: 2 columns of 10 blue dots = 20. Plus 5 purple dots = 25.
* Right Shape: 3 columns of 10 blue dots = 30. Plus 5 purple dots = 35.
* Addition: $25 + 35 = 60$

Row 14:
* Left Shape: 2 columns of 10 blue dots = 20. Plus 4 pink dots = 24.
* Right Shape: 3 columns of 10 blue dots = 30. Plus 5 green dots = 35.
* Addition: $24 + 35 = 59$
