You are placing 3251 things into 43 groups.
200
What does it mean to put a fraction in lowest terms?
Find the equivalent fraction with the smallest numerator and denominator. (24/30 in lowest terms is 4/5. There is not an equivalent fraction that uses a smaller numerator and denominator)

What do you do differently when you are ADDING fractions than when you are MULTIPLYING fractions?
When you add, you must have a common denominator, and the denominator stays the same. When you multiply, you multiply numerator by numerator and denominator by denominator.

What is the difference between a parallelogram and a rectangle?
both have 2 sets of parallel sides, but a rectangle has 4 right angles. A parallelogram only needs to have 2 sets of congruent angles.

DO NOT SOLVE. Explain the steps you would take to solve this problem:
The 5th grade students at Manch are planning a field trip to John's Amazing Pizza. There are 6 classes, and each class has 23 students. If a bus can hold 30 students, how many buses do they need to order?
1) Find the total number of students (6 x 23 = 138)
2) Find the number of buses (138 / 30 = 4 r.18)
3) Round up to the next whole number (You can't have a partial bus!) = 5 buses.
