2nd Grade Extended Response Mathematics

All Extended Response items should be scored using the ISAT rubric. Be sure a copy of the student friendly rubric for grade 2 is available to all students when they are writing their responses as well as when they are evaluating prompts. Model the extended response format frequently so students become comfortable with the process. Talking about what they did and whey they did it promotes retention of information. You are a big help to future teachers by doing this. See your Pacing Guide for suggestions on how to work on the Extended Response items. Thank you.

2nd Grade Answer Key

Students should write out their answers to show computation, to show what they did to solve the problem and why they did it. Use the state scoring rubric to evaluate student work. It is a good idea to evaluate prompts with teammates so you can share ideas.

What follows is the numeric answer only.

September: Party Shoes 42 shoes October: Library Books Yolanda has 8 books, Lucas has 4 books November: Making Pattern Blocks Blue December: Football Helmets 4 more helmets

January: Making Numbers The 5 and 6 should be in the ten’s place and the 2 and 4 should be in the one’s place in any combination. The sum would be 116. February: Ruben’s Coins 1 quarter, 1 dime, 1 nickel March: Caps for Sale Gray April: Crayon Boxes Blue 8/16 or ½ May: Playground Fence 28 yards
