Chapter Essential Questions: What are some two-dimensional shapes and three-dimensional shapes?

How can you show equal parts of shapes?

Reason with shapes and their attributes.
(1.G.1, 1.G.2, 1.G.3) / Geometry 1: Recognize and draw shapes having specified attributes, such as a given number of angles or a given number of equal faces. Identify triangles, quadrilaterals, pentagons, hexagons, and cubes.
  • I can identify three-dimensional shapes.
  • I can describe three dimensional shapes according to the number of faces, edges, and vertices.
  • I can discuss and model how to build a rectangular prism with cubes.
  • I can name 3-, 4-, 5-, and 6-sided shapes according to the number of sides and vertices.
  • I can identify angles in two-dimensional shapes.
  • I can sort two-dimensional shapes according to their attributes.
/ Reason with shapes and their attributes.
(3.G.1, 3.G.2)
Geometry 2: Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
  • I can partition rectangles into equal-size squares and find the total number of these squares.

Geometry 3: Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, or four fourths. Recognize that equal shares of identical wholes need not have the same shape.
  • I can identify and name equal parts of circles and rectangles as halves, thirds, or fourths.
  • I can partition shapes to show halves, thirds, or fourths.
  • I can identify and describe one equal part as a half of, a third of, or a fourth of a whole.
  • I can solve problems involving wholes divided into equal shares by using the strategy draw a diagram.

Each day the math block will begin with 15 minutes of Daily Math Review and Mental Math. The focus of DMR should be either prerequisite standard skills or previous chapter concepts that were not mastered. The focus of mental math should be based on the current Chapter’s skills and concepts. Adjust the amount of questions in DMR and MM to fit into the 15 minute time block.

Suggested Chapter Pacing

All lessons are paced for one day, unless otherwise indicated. Teachers may adjust to meet students’ needs.
