    • Addition: To join two or more groups. 2 + 3 =
    • Subtraction: To find the difference when two groups are compared or to find out how many are left when items are taken away from a group.
    • Equation: a mathematical statement containing an equal sign, to show that two expressions are equal
    • Addend: Any numbers being added together (Example: 3 + 4 = 7, 3 and 4 are the addends)
    • Count On: start from any given number and count forward
    • Count Back: start from any given number and count backwards
    • Equal sign (=): A symbol used to show that two amounts have the same value.
      384 = 384
    • Sum:The answer to an addition problem. In 2 + 3 = 5, 5 it is the sum.
    • Difference: The answer to a subtraction problem. In 8 – 3 = 5, 5 is the difference.
    • Number Sentence: A sentence that includes numbers, operation symbols ( +,- ), and a greater than or less than symbol ( >,< ) or equal sign. 5 + 3 = 8 25 < 32

    First Grade Geometry 

    What Your Child Will Learn

    Distinguish between defining and non-defining attributes. (1.G.1)

    Compose two or three-dimensional shapes to create a composite shape. (1.G.2)

    Partition circles and rectangles into two and four equal shares. (1.G.3)


    • Face: the flat surface of a solid figure
    • Side: a line segment joining two corners of a figure
    • Attributes: a characteristic such as shape or size
    • Angle: two rays that share an endpoint
    • Two-Dimensional: the outline of a shape
      such as a triangle, square, or rectangle
    • Three-Dimensional: a solid figure
    • Composite: made up of several different things
    • Half: 2 equal parts
    • Quarter: 4 equal parts
    • Circle: a closed round figure
    • Rectangle: a shape with four sides and four square corners
    • Square: a rectangle that has four equal sides
    • Triangle: a shape with three sides and three corners
    • Trapezoid: a four-sided shape with only two opposite sides
      that are parallel *
    • Cube: a solid with 6 faces all the same size
    • Rectangular Prism: a solid with two identical rectangular bases
    • Cone: a solid with one curved surface, one flat surface that comes to a point
    • Cylinder: a solid with one curved surface and two identical circle bases
    • Whole: all, everything, total amount

    * Students do not need to know the definition of a trapezoid. They should be able to identify it and compare it with a rectangle. Rectangles have 4 square corners and trapezoids do not.

    Activities At Home

    • Go on a shape hunt outside, ask your student to name the shapes of doors, windows, bicycle wheels, etc.
    • Ask your student to identify the shapes of various road signs while traveling in the car.
    • Talk with your student about the various shapes of items packaged in the grocery store.
    • Build with blocks. Discuss what shapes were used to create the structure.
