Math 11 27

The document summarizes a math lesson on adding fractions. It begins with the learning objectives which are to correctly add fractions with like or unlike denominators between 2 and 12 by finding a common denominator. Examples are worked through step-by-step showing how to find the common denominator and then add the numerators. Students then complete an exit ticket problem of adding 2/3 and 1/4 and an independent worksheet with 5 additional fraction addition problems to practice the skill.

I CAN correctly add fractions


BY correctly answering my exit ticket
SO THAT I better understand fractions
Success Criteria for Today
Exit Ticket: 2/3 + 1/4
Long Term Assessment
Fractions Assessment Dec. 6th
Vocabulary
common denominator, numerator, multiple
Procedure/Activites
Warm Up Question: 1/2 + 1/3

*Do NOT tell students HOW to solve the problem, but rather allow them to problem solve*
Ask students to add the fractions together on white boards.
Ask them to explain their thinking.

Then, ask them to use fraction Squares to demonstrate: if we put 1/2 together with 1/3, is it the same size as 2/5?

Say: This is why when we add fractions we need to find a common denominator, which means both fractions have the
same denominator
1. Go back to 1/2 and 1/3 on the board
2. Say: We are going to list the multiples of the denominators
3. Start with 3 and ask: The first multiple of 3 is? 3x1=3, the second multiple of 3 is? 3x2=6, the third multiple of 3 is?
3x3=9
4. Move onto the denominator of 2 and ask: The first multiple of 2 is? 2x1=2, the second multiple of 2 is? 2x2=4, the third
multiple of 3 is? 2x3=6
5. What is their least common multiple? (6)
6. Using 6 as the new denominator, work with the students to find the new numerators (they have already done this for 2
weeks with comparing & ordering fractions)
7. Now we have the fractions 3/6 and 2/6
1. Both denominators are the same, so we know our answer will also have a 6 as a denominator
2. Draw a line on the board for the fraction line, and write a 6 under the line for our answer's denominator
3. Now we just add the numerators together to get our answer's numerator (3+2=5)
4. So our answer to 1/2 + 1/3 is 5/6
5. Demonstrate with Fraction Squares: Put 1/2 together with 1/3. Is this the same size as 5/6?
Follow the same steps for another example:
1. 4/5 + 2/10
2. Find common denominator (least common multiple) and new numerators
3. add fractions
Do one more example if necessary:
1. 3/4 + 2/6
2. Find common denominator (least common multiple) and new numerators
Students complete Exit Ticket
1. 2/3 + 1/4
Independent Work: Have students choose 5 problems to complete on the Adding Fractions worksheet (attached).
