We were doing a topic on growth and I had been giving out seeds to groups of children. I came to a table of four children and was counting out the seeds so as to share them equally. I counted them out one at a time as I gave each child a seed as I went round the table.
Sara came to me later very excited and said, "When you gave out the seeds you said numbers $4, 8, 12, 16, 20, 24, 28, 32, 36, 40$ when you came to me. I was picturing the numbers in my head and realised that the units figures went $4, 8, 2, 6, 0, 4, 8, 2, 6, 0.$"
Well, I got all the children together and Sara shared what she had noticed. I then asked the children - and I'm asking you now,
"Do you think this was just something special that happened on this occasion?
Do you think it will always happen?
What do you think about the units/ones figures if a different number of children were sitting around the table"
When you've thought your ideas out I want you to prove to a friend that your ideas are right and true.
