Models+You+Can+Count+On


 * Overview**: The purpose of this unit is to introduce students to several models and tools that they can use to solve a variety of problems.


 * Section A**: The ratio table is introduced as a tool for multiplication, division, and proportional reasoning. Key strategies (adding, multiplying by 10, doubling, subtracting, multiplying, halving) are introduced and practiced.


 * Section B**: The students use bar models as a tool to represent fractions and percentages, as well as the relationship between the two.


 * Section C**: The number line is introduced as a tool for computation with whole numbers, fractions, and decimals.


 * Section D**: This section introduces the double number line (similar to a scale on a map) as a visual model for representing ratios. The students use this model to begin investigating the multiplication and division of fractions.


 * Section E**: In this section, the students are presented with a variety of contextual problems to solve using a model of their choice.
