4th Grade Math

Kami Espinoza

Rogers Creek School

Week of April 20th-24th

On the following pages, you will find this week’s assignment. It should look familiar. It is a practice on

fractions using Math Sorts which we have done before. You do not have to cut and paste, unless you

want to. You can just label the boxes with the corresponding answer. Remember, this is optional

review of material you have already learned! If you see something you do not recognize, skip it and

come back. There are 6 pages. One for each day and an extra. 😊 Shoot me an email or text. This can

be printed or viewed from a device with internet. Parents, I have included answer keys for you to

check the material and this week, you will find fraction help posters included.

Contact me if you need help! I am available Monday through Friday from 8:30-12:30.
