Discussion points for teachers

1. Find the four correct number sentences that represent the leaves and twigs.
Discuss which objects the leaves and twigs are. Discuss how many leaves and twigs there are. Discuss how the number sentences are written. Discuss how and why they are different. Discuss which number sentences match the representation correctly.
Nine = 5 + 4; Five + 4 = nine; Nine = four + five; 4 + 5 = 9

2. Which number sentences are not fact families of the leaves and twigs? How do you know?
Discuss what the other number sentences may represent. Discuss how it is different from the rest.
Two + four = 6 and 6 = four + two because they represent the twigs and feathers.  

3. Write four addition number sentences for each representation.
Discuss how the representations have been displayed. Discuss what the four number sentences are. Discuss how the number sentences are different.
Eggs: 5 + 4 = 9; 4 + 5 = 9; 9 = 5 + 4; 9 = 4 + 5. Nests: 2 + 6 = 8; 6 + 2 = 8; 8 = 2 + 6; 8 = 6 + 2. Stones: 4 + 3 = 7; 3 + 4 = 7; 7 = 4 + 3; 7 = 3 + 4. 

4. What four addition number sentences can be written for this representation?
Discuss what the representation shows. Discuss what four number sentences can be written. Discuss the different ways this can be written i.e. in words and/or numerals.
4 + 6 = 10; 6 + 4 = 10; 10 = 4 + 6; 10 = 6 + 4

5. Help Dot and Stan create 4 fact family addition number sentences for the fruits.
Discuss what the representation shows. Discuss what number sentences can be created using the different fruits. Discuss how the number sentences are different. Discuss how many different possibilities there are. This question is open-ended for children to explore.
Various answers, for example: Yellow and blue fruits: 3 + 4 = 7; 4 + 3 = 7; 7 = 3 + 4; 7 = 4 + 3 or Yellow and pink fruits: 3 + 1 = 4; 1 + 3 = 4; 4 = 3 + 1; 4 = 1 + 3

Optional discussion points:
What other objects can they count and create addition fact family number sentences for? What similarities and differences do you notice when an addition fact family with four number sentences is written?
