We learnt about different strategies of solving equations.
The first equation was 84 - 7. We knewed that we can solve this equation by written algorithm, a number line, counting backwards and spliting numbers. We showed the strategies on a DLO.
We showed the strategies we use for 6 equations and put them on a google slide.
To do 84-7, we borrow a ten from 80 that leaves us a 70 so the ten that we borrowed, we add it to the 4 that makes 14, so 14-7 is 7 so the answer is 77.
For the number line we added 3 to the 77 that makes 80 then we add a 4 to 80 that makes 84. So 3 + 4 is 7, so that proves us that 84 - 7 = 77.
For the spliting numbers we subtract 4 from 84 that gives us 80 then we subtract 3 from 80 and got the answer 77.
This activity was easy for me because I knew most of the strategies.

Hello David,
ReplyDeleteYou have an amazing blog post. I thought that you had really interesting strategies to solve the equation. Do you know any other strategies you can use to solve the equation.
