(questions came from “Performance Coach”, OAS, and various websites)

This is not meant to be printed off and given as a test…this document is to give you ideas of how this standard might be assessed. Please use these as an example when you are developing your own formative assessments. Remember formative assessment is to be given throughout the teaching of a standard to help you guide your instruction based on students needs. A good formative assessment should have a mix of multiple choice as well as open ended.

Carlos has his older soccer team run for the first 1/3 of practice. Then they do drills for 1/3 of practice. What fraction of the practice has the team completed after running and drills? Show on a visual fraction model and write an equation to match. (1/3+1/3=2/3) If they scrimmage for the rest of practice, what fraction of practice does the team scrimmage? (3/3-2/3=1/3) If practice is 90 minutes long, how long does the team run? (90÷3=30) Carlos has his younger team scrimmage for 1/2 of practice. The rest of the time is drills. What fraction of practice does the younger team do drills? (2/2-1/2=1/2) If his younger team practices for 60 minutes, which team scrimmages for a longer amount of time? (60÷2=30, so both teams scrimmage for the same amount of time.)

To build each window frame, you need 2 1/2 feet of wood for both the top and bottom and 3 1/2 feet for each side. How much wood do you need to build the window frame? Show on a visual fraction model and write an equation to match. (2 1/2 + 2 1/2 + 3 1/2 + 3 1/2 = 12) or (5/2+5/2+7/2+7/2=24/2=12 feet) If wood costs $2 per yard, how much will it cost per window frame? (12÷3)x2=$8 If you want to build 6 identical window frames, how much will it cost? (8x6=$48) What if you want to pay someone else to build the window frames? You ask a carpenter how much it would cost for the 6 windows frames. The cost would be $125 plus materials. How much would it cost for the carpenter to build the window frames? (125+48=$173)
