These are practice lessons I have put together to work with 4th and 5th graders on the second section of the Number Sense test (questions 20-40) for UIL.
Lessons include: converting fractions/decimals/percentages, prime numbers, LCM and GCD, ratios, adding and subtracting fractions, comparing fractions, and squares.
Please note, this is meant to be used with students AFTER they have mastered the lessons in the first practice book I have created.
