Without using materials children were able to solve this.
When I posed the question 53 divided by 10, Richard was able to use a different strategy and say that 50 divided by 10=5 and there were 3 left over. He knew that 5x10=50 (reversibility) and knowledge of basic facts.
Another question was 44 divided by 5. Machelle said the answer was 9 remainder 1. She said that 5x9=45-1 =44.
Richard disagreed. He said that 40 divided by 5=8 and there's 4 left over. Machelle had to repeat it back and she could see that was she had shared was incorrect. She showed understanding through discussion.
