Students used tiles to help them divide. I wrote a division fact on the board and students drew groups and used the tiles to divide. We talked about how division is about splitting an amount into smaller equal groups. We also talked about how sometimes there are left overs that we cannot divide evenly into the groups; these are called remainders.
Then students learned how to use multiplication facts to solve for division problems.
Students used skip counting to find multiplication facts.
EX: 28 / 5 = ?
First, students determined if 28 would divide evenly into 5 groups. One way we can tell if a dividend divides evenly by the divisor is if the dividend is a multiple of the divisor. I can tell 28 is not going to be divided evenly by 5 because 28 is not a multiple of 5. Students skip counted by 5s in order to find a multiple/product that was close to 28, but does not go over.
5, 10, 15, 20, 25 --- I stop at 25 because if you continue 30 is greater than 25.
We know that 5 x 5 = 25 so 28 / 5 = 5 with a remainder.
We know the difference between 25 and 28 is 3, so my remainder is 3.
