Long Multiplication

This week in maths we learnt how to solve problems using long multiplication. First we solved 20 multiplication equations using long multiplication, so we can learn and practice. After that we chose a problem and created a DLO about it using the long multiplication we learnt. Then we created screencastify explaining how to use long multiplication.

The Multiplier

LI: To solve a multiplication equation using The Multiplier. This week for maths we had to go on a multiplication site called The Multiplier. We had to solve a multiplication equation that had a 2 digit number and a 1 digit number. For The Multiplier I decided to do 83 x 6. I had to try and use strategies to solve this equation. I decided to split the equation into 83 x 3 and 83 x 3. To solve 83 x 3 I multiplied 3 and 3 which is 9. Then I multiplied 30 and 8 which is 240. After that I added 240 and 9 together which is 249. Since I solved on of the equations I don't need to solve the other because I split the 83 x 6 into 83 x 3 and 83 x 3. Then I added 249 and 249. 249 + 249 = 498. 83 x 6 = 498. I used The Multiplier by picking a multiplication equation and splitting it to solve the equation. The number that I used in the problem was 83 x 6. I split the equation by splitting the 6 into 3 and 3. Then I did 83 x 3 and 83 x 3. I split the numbers because it will be more easier to solve the equation. The easiest way to split up the numbers was to split the 6 into 3 and 3 and then multiplying it with 83 two times. I could show this equation in a diagram by telling people the steps on how to solve a equation.
