Three Test Prep / Review Worksheets for Middle School Math. GREAT for the end of the year review. These 3 worksheets (52 questions total) come with keys and relate to number sense. They cover irrational/rational numbers, absolute value, scientific notation/standard form, square root, LCM, GCF, comparing/ordering/converting fractions/decimals/percents, ratio, proportions, and tip/tax/discount, real life word problems, etc. The first worksheet is all fill in, the second is half fill in and half multiple choice, the third is all multiple choice. Thanks for looking, and I hope you find something useful!
