ECED 6263 Module 12 Check Your Understanding Problem Set
5 problems
Read the directions carefully
Be sure to use the methods asked for in the directions and to show steps so that your thinking can be understood
Your class is building a tower with building blocks for a science fair project. You have 30 blocks total. If each level of the tower needs 6 blocks, how many levels can you build with all your blocks?
You're planning a super fun video game party. You have 24 colorful game controllers and 6 gaming stations set up. If you want to divide the controllers equally among the stations, how many controllers will be at each station?
Your class is having a pizza party! The teacher ordered 45 slices of pizza. If each student's plate should have 3 slices, how many students can get a full plate of pizza?
You're setting up a super cool dinosaur exhibit in your room. You have 20 toy dinosaurs to arrange. If you want to make groups with 4 dinosaurs in each group for different time periods, how many different time period groups can you create?
For each story problem below:
Identify if the division concept is partitioning (fair-share) or measurement (repeated subtraction) then explain why.
Solve the problem using models and symbols, missing factor strategies, cluster problems, or any combination of these.
2. Solve this division problem using the Repeated Subtraction Method. Be sure to show your tracking system of related multiplication facts and partial quotients. (Hint: Check Van de Walle pages 287-290 & Division Repeated Subtraction & Explicit Trade .mp4 for guided practice on repeated subtraction.)
3. Solve this division problem using either the Repeated Subtraction Method or the Partial Quotients Method. Be sure to show your tracking system of related multiplication facts and partial quotients. (Hint: These two methods are very similar with repeated subtraction set up in a vertical format while partial quotients is set up in a horizontal format. Check Van de Walle pages 287-290 for both methods & Division Repeated Subtraction & Explicit Trade .mp4 for guided practice on repeated subtraction.)
4. Solve this division problem using the Explicit Trade Method using Base Ten Blocks. You may show the explicit trade algorithm along with your work with the blocks if you would like, but you do not have to. (Hint: Check Van de Walle page 289 & Division Repeated Subtraction & Explicit Trade .mp4 for guided practice on the explicit trade method.) There are visual base ten blocks to the right and grouping ovals below the blocks that you may use, but it just as acceptable to draw and submit scans or use concrete base ten blocks and submit pictures. Please view and listen to the .mp4 to be sure you are submitting enough steps to show your work.
