Here are the solutions to the math problems on your worksheet.
Part 1: Counting in Tens
To solve these, we add
10 to each number to get the next one. Remember that when you count by tens, the ones digit (the last number) stays exactly the same!
Row 1: Starts at 3. The ones digit is always 3.
* 3,
13,
23,
33,
43,
53,
63, 73, 83, 93
Row 2: Starts at 1. The ones digit is always 1.
* 1,
11,
21,
31,
41,
51,
61, 71, 81, 91
Row 3: Starts at 5. The ones digit is always 5.
* 5, 15, 25,
35,
45,
55,
65,
75,
85, 95

Part 2: Counting in Fives
This table asks you to fill in the missing numbers by counting up by
5. You can check your work by looking at the rows and columns.
Row 1: 5,
10,
15,
20, 25,
30,
35, 40,
45,
50
Row 2: 55, 60, 65,
70,
75, 80,
85,
90,
95, 100
Row 3: 105,
110,
115, 120,
125,
130, 135,
140,
145,
150
Row 4: 155, 160,
165,
170,
175,
180,
185,
190, 195,
200
*(Note: Since the table goes past 100, we just keep adding 5 to the previous total. For example, after 95 comes 100, then 105.)*

Part 3: Writing Number Symbols
Here, we change the written words into digits. We look at the hundreds, tens, and ones places.
1. Seven hundred and sixty four $\rightarrow$
764
2. Eight hundred and fourteen $\rightarrow$
814
3. Nine hundred and twelve $\rightarrow$
912
4. Three hundred and thirty one $\rightarrow$
331
5. Five hundred and sixteen $\rightarrow$
516
6. Two hundred and two $\rightarrow$
202 *(Be careful here! There are no tens, so we use a zero).*
Final Answer:
Counting in Tens:
Row 1: 13, 23, 33, 43, 53, 63
Row 2: 11, 21, 31, 41, 51, 61
Row 3: 35, 45, 55, 65, 75, 85
Counting in Fives (Table):
Row 1: 10, 15, 20, 30, 35, 45, 50
Row 2: 55, 70, 75, 85, 90, 95
Row 3: 105, 110, 115, 125, 130, 140, 145, 150
Row 4: 155, 165, 170, 175, 180, 185, 190, 200
Number Symbols:
