This item includes a directions sheet for students to reference and mats to sort dominos on.
Work with your partner to sort the dominoes into 3 piles:
•Make one pile of all the dominoes with an even number of dots of both sides.
•Make another pile of all the dominoes with an odd number of dots on both sides.
•Make a third pile of all the dominoes with an even number of dots on one side and an odd number of dots on the other side.
Record the dominoes in each pile on a piece of paper. Write the number of dots on each side of every domino. Record the sum for each domino.
Look at the sums on each record sheet. Talk with your partner about what you notice.
