We can count by 1s, 5s, and 10s with numbers less than 100. We have to think about the number we are counting by and say the numbers that are that many more. We use a 100 chart to see patterns with the numbers. Each number is 1 more than the number before it and 1 less than the number after it. Each number is 10 more than the number above it and 10 less than the number below it. We fill in missing numbers in a 100 chart by looking for patterns. We count on by 1s, 5s, 10s, and start counting with different numbers. We count back by different amounts starting with different numbers. We count on and back by 2s, and we count on and back by 3s. We solve a word problem that involves counting on by 5s and then by 10s.
