# Q3, W9: March 4th – 8th

Teacher Felicia Taylor Intensive Math 7th 27 Focus 2: Expressions, Equations, and Inequalities; Focus 4: Geometry
Standard(s) Taught

MAFS.7.RP.1.3

Use proportional relationships to solve multi-step ratio and percent problems.

MAFS.7.EE.1.2

Understand that rewriting an expression in different forms in a problem context can shed light on the problem and how the quantities in it are related.  For example, a + 0.05a = 1.05a means that “increase by 5%” is the same as “multiply by 1.05.”

MAFS.7.G.1.1

Solve problems involving scale drawings of geometric figures, including computing actual lengths and areas from a scale drawing and reproducing a scale drawing at a different scale.

MAFS.7.G.2.5

Use facts about supplementary, complementary, vertical and adjacent angles in a multi-step problem to write and solve simple equations for an unknown angle in a figure.

Learning Targets and Learning Criteria

Students are successful when they can…

• solve percent problems when one quantity is a certain percent more or less than another.
• use proportional reasoning to solve real-world percent problems, including those with multiple steps, such as markups, markdowns, commissions, and fees.
• recall conversion of percent’s from ratio to decimal to percent form.
• solve percent of increase/ decrease problems.
• solve problems with scale drawings of geometric figures.
• compute actual lengths and area from a scale drawing.
• reproduce a scale drawing using a different scale.
• determine actual measurements from a scale drawing.
• understand scale factor to be the constant of proportionality.
• create scale drawings in which the horizontal and vertical scales are different.
• discover the definitions of supplementary, complementary, vertical, and adjacent angles.
• solve multi-step problems by applying what you know about the types of angles.
