- illustrate equivalent ratios, using a variety of tools (e.g., concrete materials, diagrams, dynamic geometry software)
- represent, using equivalent ratios and proportions, directly proportional relationships arising from realistic situations
- solve for the unknown value in a proportion, using a variety of methods
- make comparisons using unit rates – solve problems involving ratios, rates, and directly proportional relationships in various contexts using a variety of methods
- solve problems requiring the expression of percents, fractions, and decimals in their equivalent forms
- 49 Halloween containers (find at a Dollar store)
- proportional reasoning questions
- solution handout
- Smart Notebook file with score board
- whiteboard and markers (optional)
- Halloween decorations (optional)
- prizes for winning team (optional)
- Cut out questions and place one in each of the 49 containers.
- Spread out containers on a table and add some Halloween decorations (optional).
- Bring up the scoreboard on the smartboard. (Could create your own scoreboard if a smartboard is not available)
- Place students is groups and give each student a whiteboard and marker.
- Have each group choose a Halloween bag from the scoreboard.
- One student from the group will come up and choose a container. They will bring it back to their group where all members will answer the question inside.
- One person will then come and check their answer with the teacher.
- The teacher will check off that the group has answered that question.
- The student will then drag a candy to their bag on the smartboard. Questions with no pumpkins are worth 1 candy and questions with 2 pumpkins are worth 2 candies.
- Have students place the question back in the container and choose another one. (Answered questions with container should be put to the side and put back in circulation when containers get low.)
- The group who collects the most candy will win.
Note: There are some special cards that students will find. Tap bags 1, 3, 6 or 8 on the Smartboard to play Halloween music.
