Today some students from Grade 5/6P posed the question 'can we sove division problems using the lattice method?'
First, we came up with a division problem; then we experimented with a range of possible ways the lattice method COULD be used for solving the division problem. We didn't know if our answers were right or not, so we estimated what the answer SHOULD be, then we solved the problem using a known method (short division).
Once we knew what answer we NEEDED to get, we were able to work backwards and find out how the lattice method CAN be used.
Anthony and Ajay were the first ones to work out how it could be done. Here is their explanation… (created using 'Show Me' on Miss Power's iPad).
