In developing number concepts and number sense children learn to recognize numbers as odd or even. Two books that are helpful are Even Steven and Odd Todd by Kathryn Cristaldi and Bears Odd, Bears Even by Harriet Ziefert. Opportunities to develop an understanding of odd and even numbers are bountiful throughout the school day.
1. While counting any found objects or manipulatives have the students group the items in pairs. Emphasize that an item that does not have a partner, or any ‘left over’ item is odd.
2. Have students skip-count by 2’s.
3. Give students a hundred’s chart and two crayons. Have them shade the even numbers with one color and the odd numbers with a different color.
