Students use numeral cards and mathematical symbol cards to practice simple addition and subtraction, work with number sentences, and develop systematic work habits. Students are challenged to find as many ways as possible to arrange some or all seven cards to create true statements.

The object of this activity is to match pairs of numbers and number sentences. Students click on a card to flip it, repeating until they make a match. For each match, students add 50 points to their starting score of 100. If a match is not made, students lose 10 points. The game ends when all matches have been made. Students can choose to play with 16, 20, or 24 cards.

Students can play against the computer or with a friend. The target number is given and students choose a number from 1 to 4 to add to the running total. The player who reaches the target first is the winner. The target number and the numbers to add to can be changed in the settings.

This interactive resource illustrates a change in position over time and how it can be graphed.
