Math Learning Moving from equal sharing to repeated addition

Jo did some modelling for us develop our teaching practice around moving children from equal sharing to using repeated addition.

First she ask the children to skip count in 2s, 5s, 3s. Then she ask them to identify the written form of fractions 1/2, 1/4, 1/3 and 1/10. Some of the children could identify 1/2, 1/4 and 1/3 but done could read 1/10.

She then ask the children to share some counters. She asked them to share them fairly between the monkeys. The children needed support to understand the question. She did not give them the counters. None of the children answers. So Jo asked "How could we make sure they get a fair share if I give you the counters. The child gave each five rather than equal sharing. The children said we can use our timetables.

After identify where the children were at Jo began teaching. She started with two monkeys and 8 counters. How many will each get. Children found it easier and used doubles knowledge. Followed this with adding more counters. Student were good with doubble so they moved on.

They then moved on to 3 monkeys and 12 counters. Students again used timetables and repeated addition. They then discussed what fraction they had and practiced writing fractions and learnt about the denominator telling use how many groups.

They moved on the four monkeys the children said straight away they get 1/4 because the bottom number is how many monkeys there are. 

The way Jo used word problems in the way she talked I do sometimes but perhaps I need to do this more. I also think this reinforced the need for my to continue to do fraction recognition as often as possible. Also the importance of managing children so that everyone gets thinking time. Well this is something that I try to do it does not always happen as they are so keen to share. 


  1. Isn't it great to have an expert come in to coach and provide support and new ideas?
    I like the way you have taken next steps from this and also have brought a note of realism into your reflection - it (thinking time) does not always happen as they are so keen to share! Isn't that cool in itself :)

    1. Hi Dorothy, Thank you for your comment. I really enjoying watching experts teach, you pick up on so much. I think there is a really interesting balance that we have to strike between maintaining wait time in groups and keeping the kids excited becuase that excitement is so wonderful. I am not sure I have quite got that balance right yet but I am sure I will one day.
