On paper, write out the numbers 1 through 5. Underneath each number, draw an amount of dots that is equivalent to the number; for example, draw five dots underneath the number 5. Review and count the numbers with children. Provide students with stamps and ink pads and instruct them to place a stamp on each dot underneath each number. As they are placing the stamps on the dots, encourage them to count aloud each stamp they place on the paper, which will help to form a connection of how much each number represents.
Use markers to draw the numbers 1 through 5 on the center of individual paper plates. Around the perimeter of each plate draw an amount of dots that corresponds to the number written in the center of the plate. For instance, on the plate marked with the number 4, draw four dots around the perimeter. Lay the plates on a flat surface in sequential order and count them. Provide children with clothespins and instruct them to place a clothespin on each dot on each plate. As they place the clothespins on the dots, instruct them to count aloud. For example, on the plate marked with a 2, a child should place a clothespin on each of the dots and count "1, 2" as she does so.
Use pictures of watermelons to reinforce one-to-one correspondence. Draw pictures of five watermelon slices on paper and on the center of each watermelon, write a number 1 through 5. Encourage children to count the numbers and then provide them with black markers. Instruct children to draw an amount of black dots (seeds) on each piece of watermelon that corresponds to the number written on each slice. For example, on the slice marked with the number 3, children should draw three black dots, or seeds. Have them count each seed as they draw them.
This activity develops listening skills, as well as one-to-one correspondence. Instruct your students to listen carefully as you clap and have them count aloud each clap that you make. For example, if you count four times, children should count aloud 1, 2, 3, 4. After you finish clapping, invite children to clap the same amount of times that you clapped, counting aloud with each clap that they make.
