### Identifying, Composing and Partitioning Shapes

## Standards

1.MD.B.3: Tell and write time in hours and half-hours using analog and digital clocks.

- I can recognize that analog and digital clocks are objects that measure time.
- I can identify hour hand and minute hand and distinguish between the two.
- I can identify analog and digital clocks
- I can determine where the minute hand must be when the time is to the hour (o’clock).
- I can determine where the minute hand must be when the time is to half hour (thirty).
- I can tell time to the hour using analog and digital clocks.
- I can tell time to the half-hour using analog and digital clocks.
- I can write time to the hour using analog and digital clocks.
- I can write time to the half hour using analog and digital clocks.
- I can show time to the hour and half-hour correctly using an analog clock.

1.G.A.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.

- I can identify attributes that make a shape.
- I can identify attributes that do not make the shape.
- I can classify shapes by their attributes.
- I can build shapes to show attributes.
- I can draw shapes to show attributes.

1.G.A.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.

- I can recognize that shapes can be composed and decomposed to make new shapes.
- I can describe attributes of original and composite shapes (combined shapes).
- I can determine how the original and created composite shapes (combined shapes) are alike and different.
- I can create composite shapes
- I can compose new shapes from a 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.

- I can identify when shares (parts) are equal.
- I can identify two and four equal shares (parts).
- I can describe equal shares (parts) using vocabulary; halves, fourths, and quarters, half of, fourth of, and quarter of.
- I can describe the whole as two of two or four of four equal shares (parts).
- I can justify why dividing (decomposing) a circle or rectangle into more equal shares (parts) creates smaller pieces.
