Dealing with Dominoes

Game
This domino game is designed to develop students’ concepts of equivalent units of measurement and equivalent sums of money. There is a copymaster for Supermarket Dominoes at the back of this booklet. Students will need to cut out the dominoes before playing, taking care that they cut along the solid line rather than along the dotted line so that they cut out a full domino.
To work out the rule for joining dominoes, students may need to use their set of dominoes to act out the game shown on the page. Dominoes can be joined where the matching squares contain equivalent measures or amounts of money.
Before the students play this game using the full set of Supermarket Dominoes, it is important that they have learnt about equivalent measures by investigating different containers and masses and manipulating sums of money. It is easy to find containers with capacities of 250 millilitres, 500 millilitres, 750 millilitres, 1 litre, and 1.5 litres. Ask students to discover equivalence relationships by pouring amounts from one container to the other.

Answers to Activity

1. The cards that are placed next to each other must have equal measurements.
2. Ellery can play the domino and place it beside the domino square.
