Recipe

Poor

The recipe calls for 5 ingredients or less and/or may not be clearly defined on the slides.
Fair

The recipe calls for 6-7 ingredients and is clearly defined on the slides.
Good

The recipe calls for exactly 8 ingredients and is clearly defined on the slides.
Excellent

The recipe exceeds 8 ingredients and is clearly defined on the slides.
Price comparison

Poor

There may not be tables showing distinct prices at 3 different stores for 4 different ingredients from the recipe. Work many not be shown to compute the unit price for each. The unit price may not be appropriately described. The store with the best price may not be clearly identified for each ingredient and the student writes 1 sentence or sentence fragments about their choice.

Fair

There are tables showing distinct prices at 3 different stores for 4 different ingredients from the recipe. Work many not be shown to compute the unit price for each. The unit price may not be appropriately described. The store with the best price is clearly identified for each ingredient and the student writes 2 sentences with little detail about their choice.

14 - 17 points
Good

There are tables showing distinct prices at 3 different stores for 4 different ingredients from the recipe. Some work may not be shown to compute the unit price for each. The unit price is appropriately described. The store with the best price is clearly identified for each ingredient and the student writes 2 sentences with little detail about their choice.

Quantifying the Recipe

Poor

Tables show 1 of the remaining ingredients needed, possibly with error .

The following items are given with more than 1 major error per ingredient:
- determination of whether relationship is proportional/not
- equation is provided
- constant of proportionality is given

A graph for each is inaccurately shown/missing. Colors may not be used to discern between ingredients. Points are not stated showing unit rate. Statement that describes point's meaning is missing.

0 - 13 points
Fair

3-4 of remaining ingredients are missing tables, possibly with little error.

The following items are given with 1 major error per ingredient:
- determination of whether relationship is proportional/not
- equation provided
- constant of proportionality given

An inaccurate graph for each is shown. Colors may not be used. Points are stated but not accurately showing unit rate.Statement that describes point's meaning may not show understanding.

14 - 17 points
Good

Tables show how much of each of most (1-2 missing) remaining ingredients needed

The following is given with small errors per ingredient:
- determination of whether relationship is proportional or not
- equation is provided
- constant of proportionality is given

A graph for each is accurately shown, though colors may not be used to discern ingredients. Points are stated that accurately show unit rate. Statement that describes point's meaning shows understanding.

- determination of whether relationship is proportional or not
- equation is provided
- constant of proportionality is given

A graph for each is accurately shown, colors are used to discern ingredients. Points are stated that accurately show unit rate. A statement that describes what points mean is given & shows understanding.

Comparing Amount of Ingredients

Poor

Two ingredients with accurate measurements for 1, 2, 3, and 4 batches are compared on the table. One problem is created that would require using proportional reasoning to solve based on the two ingredients. Solution may be missing.

0 - 13 points
Fair

Two ingredients with accurate measurements for 1, 2, 3, and 4 batches are compared on the table. Two problems are created that would require using proportional reasoning to solve based on the two ingredients. Solutions may be missing.

14 - 17 points
Good

Two ingredients with accurate measurements for 1, 2, 3, and 4 batches are compared on the table. Two problems are created that would require using proportional reasoning to solve based on the two ingredients. Work is limited, though the solution is given to each problem.
