Target 1​

Lesson Type:

New

Algebra

:

Variable

Solve addition and subtraction problems where a symbol is used to represent an unknown quantity.

Supporting targets:
1:

Informal introduction to variables.

2:

Explain that symbols can be anything: a question mark, a blank space, a color, a shape. The symbol is just an indication of what needs to be solved.

3:

Look closely at the problem to determine what needs to be solved, it is not always after the =.

4:

5:

Grade:

2nd

Vocabulary:

Equal, Add, Subtract, Number, Variable

Activities:

  • Students solved for the unknown quantity of the variable in an addition or subtraction equation.
  • Students used the quantities to solve equations that included the same shape or picture variables.

Target 2

Lesson Type:
Continuation
Number Operation
Computation
Work with equal groups of numbers to gain foundations for multiplication (repeated addition).

:

Supporting targets:
1:

Write an addition equation to express the sum of equal addends.

2:

Set the foundation for later exploration of multiplication (i.e. 2+2+2+2 =? How many 2s did you add? When you add 4 number 2s together, what do you get?)

3:

Use addition to find the total number of objects in an array.

4:

5:

Grade:

2nd

Vocabulary:

Row, Column, Repeat, Add, Array, Multiply, Times

Activities:

  • Students drew an array to represent a multiplication equation and wrote a matching equation using repeated addition.
  • Given a picture of an array, students wrote the corresponding multiplication and repeated addition equation.
  • Students completed a chart to show the multiplication equation, array diagram, repeated addition equation, and description of grouping in words.

Grade:

2nd

Vocabulary:

Tangrams, Flip, Slide, Rotate

Activities:

  • Students were given the silhouette of an animal and had to figure out how all 7 pieces fit into the silhouette.
  • Students flipped and rotated pieces to figure out the appropriate position for each shape.
