Unpacked Content

Knowledge

Students know:

Characteristics of additive situations.
Characteristics of multiplicative situations

Skills

Students are able to:

Compare and contrast additive vs. multiplicative contextual situations.
Identify all ratios and describe them using "For every…, there are…"
Identify a ratio as a part-to-part or a part-to whole comparison.
Represent multiplicative comparisons in ratio notation and language (e.g., using words such as "out of" or "to" before using the symbolic notation of the colon and then the fraction bar. for example, 3 out of 7, 3 to 5, 6:7 and then 4/5).

Understanding

Students understand that:

In a multiplicative comparison situation one quantity changes at a constant rate with respect to a second related quantity. -Each ratio when expressed in forms: ie 10/5, 10:5 and/or 10 to 5 can be simplified to equivalent ratios, -Explain the relationships and differences between fractions and ratios.
