**Use the counting chart. Count backward by ones. Write the numbers.** TEKS 1.5.A

Question 1.

52, 53, ___, ___, ___, ____

Answer: 52, 53, 54, 55, 56, 57.

It is a forward counting. Let’s take a look at the counting tracks. Notice the first row having 1 to 10. The second row has 11 to 20. Each number begin with 1, the second digit increases by 1 until the last column. In the third row, the pattern is the same only difference is the first digit is 2 instead of 1 and the second digit is increased by 1 until the last column. Notice that the second digit in each column is the same. Let’s skip down to 100 and the pattern continues. Now we have three-digit numbers like 101, 102, 103, 104, 105 and so on… and every third digit is increased by 1.

Question 2.

115, 116, ____, ___, __, _____

Answer: 115, 116, 117, 118, 119, 120.
