Have students sit in a circle in the center of the room. They will then take turns counting a number in order and stand up when it is their turn. The first child will say "one" and stand up, the next child will say "two" and stand up and so on with the rest of the class. Stop the children during counting on land mark numbers like five and ten. This activity will help to demonstrate to the children what the actual numbers represents. They will be able to see what "three" and "seven" looks like.
Make a set of dominoes out of construction paper that are large enough for the whole class to see. Laminate the paper and attach sticky magnets to the back in order for them to be used on the chalk board. Place a domino on the board and ask for volunteers to continue the game. Students will come up to the pile of dominoes and find one that will play correctly on the board. During this activity, the students will gain number sense by picking out the correct corresponding number of dots on dominoes.
Give each student ten dried beans. Have the children practice math with the beans by giving them simple, practical word problems to solve. An example problem would be; Sally has two beans and Joey gives her three more; how many beans does Sally have now? The students can use the beans to represent the different items in the story. This will give them a physical representation to understand the numbers in the problem.
Use a "100 Chart" in the front of the room to show relationships between different numbers. These charts can be used to demonstrate counting by 2s, 5s and 10s. Have the students work together as a class to fill in a blank number chart, completing one number per day and celebrate completion on the 100th day of school. Near the end of the kindergarten year, when students have better mastery of number sense, they can create their own 100 chart.
