Math Activity

I think it is important for students to know the basics of math! This includes adding and subtracting without the use of a calculator.

Students, we have been having difficulty in math adding and subtracting large numbers.
In class we have been learning different mental strategies to break down the numbers into a simpler question. Please refer to the game below for practice! Everyone has been doing an amazing job - Keep up the great work!

Practice!!

Parents, below is  the math expectations that this game covers. Students should be working on improving a variety of mental math strategies.

This game is beneficial as students can pick their level of difficulty. Therefore, students should start at a lower level and work their way up - increasing their confidence! As well, this game also provides students with the right answer in case they may have got a question wrong so they can continue to learn as the game proceeds.

I have provided examples to explain what we have been exploring in class.
We have been practicing a lot in class but I believe it would be beneficial for students to practice these math skills at home on a weekly basis.

By the end of grade 4, students will: add and subtract two-digit numbers, using a variety of mental strategies (e.g., one way to calculate 73 – 39 is to subtract 40 from 73 to get 33, and then add 1 back to get 34);

By the end of grade 4, students will: solve problems involving the addition and subtraction of four-digit numbers, using student-generated algorithms and standard algorithms (e.g., “I added 4217 + 1914 using 5000 + 1100 + 20 + 11.”);
