Domino Sorting

This problem helps learners become more familiar with odd and even numbers and addition facts within five. By challenging them to justify their findings, it also develops reasoning and communication skills. The problem displays 9 dominoes and asks the student to sort them according to parity, and then into pairs totaling 5 pips. It poses questions that stimulate thinking about basic number concepts. The Teachers' Notes page offers suggestions for implementation, discussion questions, ideas for extension and support, and a link to an interactive Dominoes Environment (cataloged separately).

    • A nice activity that addresses several aspects of number sense. A basic activity with dominoes that can acquaint students with them and set up the more sophisticated domino problems that NRICH offers. Parity is very useful in p/s.
