Students: Area Students know: Students understand that/are Recognize EE3.G.2. Level IV Students will: Given squares, able to: that shapes can be EE3.G.2. Given shapes with multiple lines of symmetry, will be able to identify equal rectangles, or circles, partitioned into equal areas. Partition Strategies for areas. Ex. Complete simple tangram puzzles with tangram pieces. decomposing shapes Decompose circles, squares, Ex. Identify equal areas on complex shapes (i.e., stars, rectangle cut on the diagonal)* Cut or draw lines to into equal shares, and rectangles into equal divide the shapes into shares, Level III Students will: equal shares and Fraction vocabulary; EE3.G.2. Recognize that shapes can be partitioned into equal areas. justify their divisions halves, thirds, fourths, Communicate the size of Ex. Given a shape, cut the shape into equal areas. by reasoning about quarters, fifths, eighths, shares using the appropriate Ex. Cut a pizza into equal areas to hand out to students in the class. equal area, and tenths. fraction terminology, Level II Students will: Express the area of Justify equal area of EE3.G.2. Create shapes. each part as a unit congruent and Ex. Work a pattern block puzzle that results in a shape. fraction of the whole shares as equal Ex. Given three small rectangles, rearrange them into a larger rectangle. (e.g., partition a shape shares of the same size into 4 parts with equal whole. Level I Students will: area, and describe the EE3.G.2. Match shapes. area of each part as 1/4 The same fractional parts of Ex.
