Discussion points for teachers

1. Help Cleo and the baker work out how many loaves he sold by using related facts.
Discuss counting the sacks in 10s and how the number of sacks relate to the number of loaves.
6 sacks – 2 sacks = 4 sacks so 60 loaves – 20 loaves = 40 loaves.

2. How many loaves does the baker need to make for these ships?
Discuss the similarities between this and the baker’s problem. Discuss the most sensible way to count the marks to see how many people are on board each ship.
2 marks + 5 marks = 7 marks so 20 people + 50 people = 70 people altogether. 3 marks + 6 marks = 9 marks so 30 people + 60 people = 90 people altogether.

3. Help Cleo to work out what the missing numbers should be.
Discuss how to deduce the missing information using the information in the other related facts. Discuss that if we know  4 + 5 = 9 then we know 40 + ? = 90. Discuss how the final number statement could have multiple different answers. This question is open-ended for the children to explore.
This Week: 4 + 5 = 9, Next Week: 40 + 50 = 90.
This Week: 1 + 7 = 8, Next Week: 10 + 70 = 80.  This Week: 8 + 2 = 10, Next Week: 80 + 20 = 100.
Various answers, for example: This Week: 6 + 1 = 7, Next Week: 60 + 10 = 70.

Optional discussion points:
Can these related facts be used with any other numbers? Does it only work for tens?
