Standard

Build and draw shapes having specific characteristics.

Core Standard

1.G.1 Distinguish between defining attributes (e.g., triangles are closed and three-sided) versus non-defining attributes (e.g., color, orientation, overall size); build and draw shapes to possess defining attributes.

1.G.2 Compose two-dimensional shapes (rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) or three-dimensional 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.

In Other Words

Students can use 2 dimensional shapes (circles, triangles, squares, rectangles, etc.) and 3 dimensional shapes (cubes, cylinders, cones, etc.) to create a new complete shape. 

If Mastered

Go to illuminations.nctm.org and click on k-2, then search, scroll down to Patch Tool, Shape Tool. Students play games to show mastery.                   

If Not Yet Mastered

Go to illuminations.nctm.org and click on k-2, then search, scroll down to Patch Tool, or Shape Tool. Student and parent play games together discussing the answers until student can play the game on their own.               

Standard

Divide circles and rectangles into halves and fourths.

Core Standard

1.G.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.

In Other Words

Students will be able to divide a circle and rectangle in two and four equal shares. 

If Mastered

Go to www.sheppardsoftware.com, click on math games, then click on early math k-2, scroll down to fractions. Student can play Fraction Shoot to show mastery of halves and fourths. 

If Not Yet Mastered

Go to www.sheppardsoftward.com, click on math games, then click on early math k-2, scroll down to fractions. Student and parents can play Fraction Shoot and discuss answers until student can play the game on their own.
