Grade: 1, Topic(s): counting and cardinality

## Purpose

To practice “counting on” from a given number fluently.

Tell children that you are going to start counting and after a few numbers, you will stop. Children are to continue counting from the last number you say. You might begin with the following sequences:

The teen numbers may be difficult for some children, and many young children have difficulty crossing over a decade. You may want to do this activity with individual children so that you can identify strengths and weaknesses in counting. You can also use this activity throughout the year as children become more familiar with larger numbers.

Part 1 focuses on starting with numbers ending in 0–5. Part 2 builds to crossing over “decades.” The extension incorporates counting on with numbers greater than 90.

*While children are enjoying their building of mastery, feel free to repeat. When children are eager for more, try Part 2.*

I’m going to start counting and after I say a few numbers, you keep going. (This time, pay special attention to crossing into a new decade, like 9, 10, 11 or 29, 30, 31).

** ***As always, when children seem excited for a new challenge, move on.*

I’m going to start counting and after I say a few numbers, you keep going. This time we’ll try with numbers greater than 90.
