4th+Grade+Math+Review

**4th Grade Math Review** This page will serve as a review for 4th grade math concepts students seem to be struggling with. This will help you make test corrections and review skills from last year. In addition, please work on your child's addition, subtraction, multiplication, and division facts. All need to be known through the 10s. Addition goes from 0+0 to 10+10 in every possible combination on the speed test (meaning 8+9 and 9+8 are both on there etc). Subtraction goes from 20-10 to 0-0. Multiplication begins with 0x0 and ends with 10x10 in every possible combination (3x4 and 4x3 etc). Division is 1/1 to 100/1. Each test will contain 121 problems (all of the same procedure) and students will have 2 minutes to complete them. I am working on obtaining the songs I learned my multiplication tables to from my own 3rd grade teacher. When I do, you will be notified, and if you would like them you may send in a blank CD and I will burn the songs for you.

Where the instructor in this video writes "100, 20, 50" etc, I like the students to write out the base facts. For example, in this problem, on the left side of the page, students should write:

6x1=6 6x2=12 6x5=30 6x10=60 <span style="color: #800000; font-family: 'Courier New',Courier,monospace; font-size: 150%;">6x20=120 <span style="color: #800000; font-family: 'Courier New',Courier,monospace; font-size: 150%;">6x50=300 <span style="color: #800000; font-family: 'Courier New',Courier,monospace; font-size: 150%;">6x100=600

<span style="color: #800000; font-family: 'Courier New',Courier,monospace; font-size: 150%;">It is easy for students to remember their 2, 5, and 10 times tables. bumping up to 20, 50, 100, etc means you simply add a "0" onto the end (ex. 6x2=12; 6x20=120). Students should then only use 2, 5, 10, 20, 50, 100, and 1 on the right hand side. The second video shows how to do big 7 when you have a remainder.
