**Two Numbers**. In this game, children practice recognizing written numerals and placing them in the correct order, using one-to-one correspondence when counting, subitizing, decomposing and composing numbers. Playing can help them develop a mental number line they can visualize in their minds. First, children set out their cards in order from 1 to 5, 1 to 10, or even 0 to 12. Children take turns rolling the dot cubes and turn over whatever cards they can based on the roll. All children can turn over their cards regardless of which child rolled the dice—they are “sharing the roll.” If they roll a 2 and a 3 they may turn over their 2 and 3 cards, *or* the sum, 5, *or* use whatever other operations players agree on at the start. If no card can be turned, the player waits for the next roll. Children try to turn over all of their cards.

*Mouse Counts **by Ellen Stoll Walsh
*The snake is gathering up the mice and counting them (“1, 2, 3”, up to 10) as he puts them in a jar to eat later. When he goes off to gather up one really big mouse, the 10 mice tip over the jar and escape! They “uncount” themselves 10, 9, 8, 7, 6, 5, 4, 3, 2, 1. This adorable story is great for practicing counting forwards and backwards.

To extend the learning in this book you could make 10 mice. Have children act out the counting in the book by placing them in a clear container, then have them escape and counting backwards.

** How Many Snails: A counting book** by Paul Giganti, Jr., illustrated by Donald Crews

Walking to the meadow, lake, library, park, bakery, toy store, and other stops, the author wonders ‘how many?’ about a variety of different objects and in different combinations; such as: “How many snails were there? How many snails had striped shells? How many snails had striped shells and stuck their heads out?” This is a fun counting book to use as a read aloud and then for children to browse on their own counting all the objects and sorting them into different groups. It specifically targets the skills of cardinality—knowing how many in all in a group. This skill is associated with stronger mathematics achievement later in school, so make sure to practice it in preschool!

*Math Counts: Numbers** by Henry Pluckrose
*This book is great for using a few pages at a time to talk about all the places we see and use numbers in our world. You can have the children go on a Number Hunt to find and identify the numbers on the page and then find and identify numbers in the classroom, at the center, outside, and at home. Children could create pictures that include numbers they like.
