Discussion points for teachers

1.Which piles of stones could Dot carry back?
Discuss the amount in the different piles of stones. Which combination of two piles would provide you with a number bond less than 10? What number is the biggest you could create without going over 10? This question is open-ended for children to explore.
Accept various combinations, as long as both numbers create a number bond less than 10. Various answers, for example: 6 + 3 = 9

2.Is Dot correct?
Discuss what the number created would be when adding 6 to 6. Would this meet her criteria? Why?
No. This would create a number bond to 12; 6 + 6 = 12

3.Who has collected the most stones?
Discuss the number of stones both Dot and Stan have presented. What number bonds have they shown?
Dot has collected the most stones. She has 9 whereas Stan only has 8.

4.Stan says he has collected the greatest number of stones because his are bigger. Is he correct?
Discuss whether the number of stones changes when taking size into consideration. Will this impact on the number bonds shown?
No. The number bonds do not change.

5.Which bushes could Dot have chosen?
Discuss the number that would meet Dot’s criteria. Looking at the number of berries on each bush, which number bonds could be created which will be more than 6, but less than 10? Which combinations would you create using the number of berries shown on each bush? This question is open-ended for children to explore.
Accept various combinations, as long as both numbers create a number bond of 7, 8 or 9. Various answers, for example: 6 + 2 = 8

6.Who has collected the most berries? Use the symbols >, < or = to compare the berries.
Discuss the number of berries both Dot and Stan have presented. What number bonds have they shown? Discuss how a symbol can be used to compare these numbers.
They both have 8 berries each so they have an equal amount. 8 = 8

7.Stan says he has collected the most berries. Is he correct?
Discuss whether the number of berries changes when taking type into consideration. Will this impact on the number bonds shown?
No. They have collected an equal number of berries.

8.Who has the most berries now? Use the symbols >, < or = to compare the berries.
Discuss the new number bond Stan has presented to you. Will this affect who has the most? Discuss how a symbol can be used to compare these numbers.
Stan now has more because he has 9 berries and Dot has 7 berries.  7 < 9
