This activity is designed to see if students are able to apply their addition strategies in order to find the total of their collection of cards. Often students will have a method for adding two numbers, but when asked to add a list of numbers they revert to less efficient methods.
Purpose
- Use efficient strategies to find the total when adding a collection of playing cards
- Recall and apply addition facts
- Identify and continue number patterns resulting from addition
- Explain strategy used to find total
Curriculum Connections: VICTORIAN CURRICULUM F-10
Number & Place Value – Year 3
- Recall addition facts for single-digit numbers and related subtraction facts to develop increasingly efficient mental strategies for computation(VCMNA133)
- Recognise and explain the connection between addition and subtraction (VCMNA132)
At the end of this lesson students should be able to answer the following questions
- What strategy are you using to collect the cards?
- Is this the most effective strategy?
- What strategies can help you add the total of your collection of cards?
- Is there a more efficient strategy?
- Does it matter in what order you add the cards?
- What is the most efficient way to add the cards?
- Can you combine two of the numbers then count on?
- Can skip counting or multiplication facts help you?
- What other strategies could you use?
- Have you tried keeping a running total?
