The document describes a cross-curricular art lesson plan utilizing ratios and proportions. Students will be introduced to the concepts of ratio and proportion, and how they apply to art. They will use ratio and proportion to enlarge small photocopied images onto larger pieces of paper to create collaborative classroom displays of portraits honoring famous artists like Van Gogh, Kahlo, Lawrence, and others. The lesson incorporates common core math standards around ratios and proportional relationships.

20. The process...!! ! ! ! !
first be
to the terms
• Students will and howintroducedbe applied to “ratio” and
“proportion”
they can
art
• Ratio: a comparison of two numbers (1 inch to 1 foot)
ratios (comparing
• Proportion: a comparison of two equal the length of the the
length of one line on a small square to
same line on a larger square)
• Common Core Standards:
•
•
CCSS.Math.Content.7.RP.A.1 Compute unit rates associated with ratios of fractions, including
ratios of lengths, areas and other quantities measured in like or different units.
•
Sunday, November 10, 13
CCSS.Math.Content.6.RP.A.1 Understand the concept of a ratio and use ratio language to
describe a ratio relationship between two quantities.
CCSS.Math.Content.7.RP.A.2 Recognize and represent proportional relationships between
quantities.

22. The process...
•
Students will be given a small photocopied square
and a larger piece of blank paper or poster board
•
Students will use ratio and proportion to transfer the
photocopied image on to their paper.
•
After they students finish with pencil, I approve the
drawing and they go over it with sharpie.
