1st Grade Unit 6 At a Glance (Parent Letter)

By the end of the unit students should be able to:

• I can define a shape.

• I can identify, name, build, and draw various plane (2D) shapes (triangles, rectangles, squares, trapezoids, hexagons, circles). (NC.1.G.1)

• I can identify, name, build various solid (3D) shapes (cubes, rectangular prisms, cones, cylinders). (NC.1.G.1)

• I can describe the defining and non-defining attributes of 2D or 3D shapes

• I can create composite shapes.

• I can create 2-dimensional composite shapes using other 2-dimensional shapes (triangles, rectangles, squares, hexagons, trapezoids, circles & half-circles). (NC.1.G.2)

• I can create 3-dimensional composite shapes using other 3-dimensional shapes (cones, spheres, cylinders, rectangular prisms, cubes). (NC.1.G.2)

Unit 7: Partitioning and Telling Time to the Half Hour                                                                                                                       1st Grade Unit 7 At a Glance (Parent letter)

By the end of the unit students should be able to:

• I can explain why we need to tell time.

• I can tell and write time to the hour and half hour on an analog and digital clock. (NC.1.MD.3)

• I can explain when we use equal shares.

• I can partition circles and rectangles into equal shares (halves and fourths). (NC.1.G.3)

• I can describe two equal shares as halves and four equal shares as fourths. (NC.1.G.3)

• I can describe the whole as two of or four of the shares when partitioning shapes.  (NC.1.G.3)

• I can explain why creating more shares creates smaller shares. (NC.1.G.3)

 1st Grade Unit 8 At a Glance (Parent letter)

By the end of the unit students should be able to:

• I can show flexibility when working with numbers

• I can solve addition & subtraction word problems within 20 using a strategy that efficiently leads to an accurate answer. (NC.1.OA.1)

• I can solve addition and subtraction problems within 20 using a variety of strategies (counting on, making ten, decomposing a number leading to a ten, using the relationship between addition and subtraction, using a number line, creating equivalent but simpler or known sums). (NC.1.OA.6)

• I can solve word problems involving three addends using a strategy. (NC.1.OA.2)

• I  can use the commutative or associative properties of addition to add. (NC.1.OA.3)
