Common Core Math

Priority Standards for the Year

Operations and Algebraic Thinking

 

                                                    1.OA.1. Use addition and subtraction within 20.

Number & Operations in Base Ten

 

1.NBT.1. Count to 120.

1.NBT.2. Understand that the two digits of a two-digit number represent amounts of tens and ones

Measurement & Data

 

1.MD.1. Order three objects by length; compare the lengths of two objects indirectly by using a third object.

1.MD.2. Express the length of an object as a whole number of length units, by laying multiple copies of a shorter object (the length unit) end to end; understand that the length measurement of an object is the number of same-size length units that span it with no gaps or overlaps.

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

 

Geometry

 

1.G.1. Distinguish between 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.

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.

 

Children need to recognize numbers to 30 in order & out of order
