MAT-01.G.03

MAT-01 Targeted Standards
(G) Domain: Geometry
Cluster: Reason with shapes and their attributes.

MAT-01.G.03 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.

Student Learning Targets:

Knowledge Targets

Reasoning Targets

  • I can understand that halves (half) show two equal parts of a whole.
  • I can understand that fourths (quarters) show four equal parts of a whole.

Skills (Performance) Targets

  • I can divide circles and rectangles into 2 and 4 equal parts to show one half and one quarter.
  • I can find shapes that show halves and fourths.

In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content.

-
  3.5 In addition to Score 3.0 performance, the student demonstrates in-depth inferences and applications regarding the more complex content with partial success.
3.0

Student is able to 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. Student demonstrates understanding of fraction concepts with little error.

I can divide circles and rectangles to show half.

I can divide circles and rectangles into quarters.

I can color one half and one quarter of a shape.

I can find shapes that show halves and fourths having equal parts.

-
  2.5 No major errors or emissions regarding 2.0 content and partial knowledge of the 3.0 content.
2.0

Student is able to demonstrate understanding that halves have two equal shares and fourths/quarters contain four parts, but may have errors in identifying fourths as equal parts.

I can divide a shape into 4 parts when asked to show quarters or fourths.

I can sometimes find shapes that show fourths have all equal parts.

-
  1.5 In addition to 1.0 content, student has partial knowledge of the 2.0 and/or 3.0 content.
1.0

Student is able to demonstrate beginning understanding that halves contain 2 parts, but may have errors in identifying halves as equal parts.

I can divide a shape into two parts when asked to show half.

I can sometimes find shapes that show halves have equal parts.

-
  0.5 Limited or no understanding of the skill is demonstrated.
