A class are skip counting. 64, 69, what, 79, what. What number should Charlotte say? What number should Noah say?

Charlotte and Noah are skip counting by fives. Sometimes when we count by fives, we start at zero. Five, 10, 15, 20, 25, and so on. Charlotte and Noah’s class started skip counting by fives at number 64. 64, 69, the missing number, 79, and Noah’s missing number.

Let’s think about Charlotte’s number. What number is five more than 69? 70, 71, 72, 73, 74. Charlotte should say number 74. What number should Noah say? 64, 69, 74, 79. Did you notice the pattern? Six tens, four ones; six tens, nine ones; seven tens, four ones; seven tens and nine ones. The next number in the sequence is 84. Noah should say number 84. And Charlotte should say number 74. 64, 69, 74, 79, 84.

The missing numbers were 74 and 84.
