Reviewing Ratios

I Can…. explain the meaning of ratios

Reviewing Ratios When: The question asks me to explain the meaning. How: First, I must decide if it is a part to part, part to whole, or whole to part comparison. If it is a part to part comparison, I can read the ratio left to write. If it is a part to whole or a whole to part, I must discuss the whole before the part Example: part to part: “For every ___ _____, there are ____ ________.” Part to whole or whole to part: Out of every __________, ________ are I can check my answer by: Comparing my explanation to the question, or drawing a diagram of my explanation.

I Can…. Create and use a ratio table, by scaling a given ratio up and/or down.

Reviewing Ratio Tables When: The question asks me to create a ratio table. The question asks me to complete the given ratio table. I need a visual to solve a missing quantity. How: Ratio tables can be created by, listing the words and quantities given in a horizontal or vertical table. I can extend a ratio table, by multiplying both quantities by the same number. I can simplify a ratio or scale a ratio down, by dividing each quantity by the same number. Sometimes, I have to scale a ratio down before I can scale forward. Example: I can check my answer by: Cross Multiplying any two ratios in the table.

I Can…. Find a missing quantity using a given ratio.

Reviewing Equivalent Ratios When: The question gives 3 quantities and asks me to find the 4 th quantity. The question asks me to use a ratio to find a quantity. The question asks me to complete the ratio table. How: I can use a ratio table to organize my thoughts and give me a visual. I must be careful to list the quantities in the order they are listed in the question. I must figure out how the ratio is being scaled (up or down) and by how much. Sometimes I may have to scale down, before I can scale up. I can also use cross multiplication and division to find equivalent cross products. Examples: I can check my answer by: cross multiplying the original ratio and the ratio I created.
