Math Curriculum

1st Grade

Course Purpose:

Students will use numbers to represent, solve, and apply the properties and relationship of addition and subtraction with use of place value to solve problems. Students will fluently add and subtract within 20 as they extend the counting sequence.

Outcomes and Components:

M.1.8

   Students will distinguish between defining and non-defining attributes, compose two-dimensional  and three-dimensional shapes, and partition two-dimensional shapes into equal shares.

Standard(s)
    M.1.8.1   Distinguish between defining attributes and non defining attributes of shapes. 1.G.A.1
    M.1.8.2   Build and draw shapes to possess defining attributes. 1.G.A.1
    M.1.8.3   Compose two-dimensional shapes (to include rectangles, squares, trapezoids, triangles, half-circles, and quarter-circles) to create a composite shape and compose new shapes from the composite shape. 1.G.A.2
    M.1.8.4   Compose three-dimensional shapes to include cubes, rectangular prisms, cones, and cylinders to create a composite shape and compose new shapes from the composite shape. 1.G.A.2
    M.1.8.5   Describe a whole as two of, or four of, the equal shares and understand that decomposing shapes into equal shares creates smaller shares. 1.G.A.3
    M.1.8.6   Partition circles and rectangles into two and four equal shares, describing the shares using halves, fourths, and quarters 1.G.A.3
