Odd and Even: Pair the Dots
Ten groups of dots to pair up. If every dot has a partner the number is even; if one is left over it is odd.
Count tally marks in bundles of five and write the number, then draw tallies for a number.
“Count the tallies by fives, then ones. Write the number. Then draw tallies for the last ones!”
Show why the fifth mark crosses the bundle: groups of five are faster to count. Then let kids tally something real, like votes.
Kids who recount the whole group instead of counting on. Ask, “You already know there are 5 here. What comes next?”
Play “I’m thinking of a number” with clues like more than 12 and less than 15.
