Essential Questions:
Unit 3 instructional time is focused on two power standards:
1.G.A.2 Compose twodimensional shapes (rectangles, squares, trapezoids, triangles, halfcircles, and quartercircles) or threedimensional shapes (cubes, right rectangular prisms, right circular cones, and right circular cylinders) to create a composite shape, and compose new shapes from the composite shape.
1.G.A.3 Partition circles and rectangles into two and four equal shares, describe the shares using the words halves, fourths, and quarters, and use the phrases half of, fourth of, and quarter of. Describe the whole as two of, or four of the shares. Understand for these examples that decomposing into more equal shares creates smaller shares.
Unit 3 instruction is supported by the following standards:
1.G.A.1 Distinguish between defining attributes (e.g., triangles are closed and threesided) versus nondefining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.
1.MD.B.3 Tell and write time in hours and halfhours using analog and digital clocks.
1.OA.A.2 Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.
1.MD.C.4 Organize, represent, and interpret data with up to three categories; ask and answer questions about the total number of data points, how many in each category, and how many more or less are in one category than in another.
 How are shapes used in our world?
 What makes shapes different from each other? What are attributes?
 How can I create a shape?
 How do shapes fit together and come apart?
 How can we divide shapes into equal parts?

 compare, contrast, and/or classify geometric shapes using position, shape, size, number of sides and number of angles
 solve simple problems, including those involving spatial relationships
 investigate and predict the results of putting together and taking apart twoand threedimensional shapes
 be able to divide a whole shape (circles and rectangles) into equal parts (halves, fourths).
