Here are the solutions for the addition problems on the worksheets. I have grouped them by the type of problem shown on each sheet.
Sheet 1: Horizontal Addition
*Add the numbers across.*
* $10 + 3 = \mathbf{13}$
* $93 + 4 = \mathbf{97}$
* $63 + 5 = \mathbf{68}$
* $37 + 7 = \mathbf{44}$
* $57 + 4 = \mathbf{61}$
* $83 + 5 = \mathbf{88}$
* $28 + 9 = \mathbf{37}$
* $88 + 7 = \mathbf{95}$
* $43 + 6 = \mathbf{49}$
* $27 + 9 = \mathbf{36}$
* $55 + 5 = \mathbf{60}$
* $47 + 6 = \mathbf{53}$
* $72 + 8 = \mathbf{80}$
* $90 + 8 = \mathbf{98}$
---
Sheet 2: Vertical Addition (No Regrouping)
*Stack the numbers and add straight down.*
* $24 + 6 = \mathbf{30}$
* $92 + 8 = \mathbf{100}$
* $66 + 9 = \mathbf{75}$
* $74 + 5 = \mathbf{79}$
* $88 + 6 = \mathbf{94}$
* $96 + 7 = \mathbf{103}$
* $56 + 5 = \mathbf{61}$
* $41 + 9 = \mathbf{50}$
* $29 + 8 = \mathbf{37}$
* $53 + 9 = \mathbf{62}$
* $63 + 7 = \mathbf{70}$
* $35 + 5 = \mathbf{40}$
---
Sheet 3: Small Vertical Addition
*These are smaller numbers stacked vertically.*
* $6 + 3 = \mathbf{9}$
* $2 + 4 = \mathbf{6}$
* $5 + 1 = \mathbf{6}$
* $8 + 2 = \mathbf{10}$
* $7 + 3 = \mathbf{10}$
* $2 + 7 = \mathbf{9}$
* $9 + 1 = \mathbf{10}$
* $5 + 2 = \mathbf{7}$
* $6 + 4 = \mathbf{10}$
* $2 + 2 = \mathbf{4}$
* $5 + 7 = \mathbf{12}$
* $7 + 2 = \mathbf{9}$
* $5 + 3 = \mathbf{8}$
* $2 + 9 = \mathbf{11}$
* $4 + 1 = \mathbf{5}$
* $5 + 7 = \mathbf{12}$

Sheet 4: Domino Addition
*Count the dots on each side of the domino to find the numbers, then add them.*
1.
Top Left: 1 dot + 1 dot $\rightarrow$ $1 + 1 = \mathbf{2}$
2.
Top Right: 5 dots + 1 dot $\rightarrow$ $5 + 1 = \mathbf{6}$
3.
Middle Left: 3 dots + 2 dots $\rightarrow$ $3 + 2 = \mathbf{5}$
4.
Middle Right: 6 dots + 1 dot $\rightarrow$ $6 + 1 = \mathbf{7}$
5.
Bottom Left: 4 dots + 2 dots $\rightarrow$ $4 + 2 = \mathbf{6}$
6.
Bottom Right: 2 dots + 3 dots $\rightarrow$ $2 + 3 = \mathbf{5}$
---
Sheet 5: Two-Digit Vertical Addition
*Add the ones column first, then the tens column.*
* $94 + 12 = \mathbf{106}$
* $54 + 52 = \mathbf{106}$
* $99 + 19 = \mathbf{118}$
* $82 + 45 = \mathbf{127}$
* $88 + 49 = \mathbf{137}$
* $35 + 15 = \mathbf{50}$
* $76 + 22 = \mathbf{98}$
* $41 + 16 = \mathbf{57}$
* $67 + 33 = \mathbf{100}$
