**Grade level : K - 6**

**Objective: **To motivate students to think like mathematicians
while interacting in the classroom math centers and
in real world situations.
This lesson is designed to awaken the mathematician within the student.

**Vocabulary List:**

add

subtract

divide

multiply

count

product

quotient

multiplicand

Do you know what a mathematician is?

Students will create and maintain a list of math terms from K through 6 as the lesson progresses.

Get ready to count!

4 - 6B Start the lesson with this riddles. What does it take to make a whole pizza? Answer: Common pieces. Explanation" when adding fractions you must have common denominators.

Common Denominators

**This lesson plan corresponds to
Specific Curriculum Outcome:
**Grade 4: B6

**Objectives:
**The students will use models informally to add simple fractions
with common
denominators.

**Materials:
**Square tiles, pattern blocks, drawing paper, rulers, coloring
pencils

**Procedure:
**By constructing symmetric shapes with smaller and congruent pieces,
the
students will learn to add fractions with the same denominators.
They will
also learn to equate certain fractions with others that have different
denominators.

- Draw a pizza on the board and divide it into halves. Ask the students how many pizzas there are on the board. Ask them how many halves there are in one pizza.
- In groups of 2 or 3, the students will create symmetric shapes with square blocks. Circulate, using the shapes they have created to ask, for example, how many quarters there are in one half, etc.
- The students will continue the activity with pattern
blocks. With these blocks, they may create symmetric shapes other
than rectangles or squares.

Circulate as before. - Each student will divide a piece of drawing paper into 8 sections
and color it as follows:

- 3/8 in 1 color

- 1/4 in another color

- each of the remaining eighths in different colors

**Evaluation:
**The students will be evaluated on their class work and on a quiz.

Using the calculator is as easy as 1 2 3!
