In this activity the students play a card game to practice their addition and subtractions facts.
Create and solve number problems using the basic operations of addition and subtraction.
Sets of cards with numbers 1-10 (decks of cards with face cards removed could be used)
- Explain that the students are going to use the cards to practice their basic facts.
- Shuffle the number cards and deal two cards. Shuffle the operations cards and deal one. Show these to the students.
- Ask students to suggest how the three cards could be used to make a number question, which they could answer. For example if they drew 3, 5, and +, they could make 3+5, or 5+3, both of which they could answer. If they drew the – they might not be able to solve the problem with the negative solution.
- Provide students with cards (one set for two or three students) and set the task.
- Students to record their questions and answers.
Ask: How many different questions can be made? - As an extension students could draw 3 number cards and two operation cards (not all cards need to be used in each question).
How many different questions can be made? - Encourage students to identify in which cases the answers to questions are the same
