Standard: MAFS.2.OA.1.a (DOK 2)
Monday

2. Learning Goal
Students will solve addition and subtraction word problems.

3. Objective
Students will be able determine the unknown whole number in an equation relating four or more whole numbers.
Students will be able to determine if an equation relating four or more whole numbers is true or not true.
Ask the students what does this mean? Why is this important?

4. Scale
3- I can, with no help, determine if an equation relating four or more whole numbers is true or not true.
2- I can, with limited help, determine if an equation relating four or more whole numbers is true or not true.
1- I need a lot of help to determine determine if an equation relating four or more whole numbers is true or not true.
0- I can’t, even with help, determine if an equation relating four or more whole numbers is true or not true.

5. Bell ringer
Is the following true or not true? = True Not True = True Not True = True Not True = True Not True
Make sure you have a discussion with the students. Have them to explain why the answer is true or not true.

6. H.O.T. to consider during the lesson
1. How can we compare equations to determine if the statement is true or not true?

7. How to determine if a math statement is true or not true.
Lets look at the math statement =
First I must solve the first equation, =
then I must solve the second
equation.
Both equations equal the same sum so I know that = is a true math statement.
Compare equations to determine if the statement is true or not true.

8. Another example Lets look at the math statement 155 + 23 = 123 + 50.
First I must solve the first equation: = 178
Then I must solve the second equation = 173
The equations do not have the same sum so this math statement is not true. =
Compare equations to determine if the statement is true or not true.

9. Objective reminder
Students will be able determine the unknown whole number in an equation relating four or more whole numbers.
Students will be able to determine if an equation relating four or more whole numbers is true or not true.
Add this point facilitate a discuss as to why we need to be able to tell if equation are true or not true. Turn and Talk: How can this help us in real life?

10. Kagan Structure- Hand Up, Stand Up, Pair up
All student must determine if the following math statements are true or not true.
Use drawings and models to help determine your answers.
– 15 = =
Partner A shares their answer for #1 and how they reached that determination.
Partner B shares their answer for # 2 and how they reached that determination
Compare equations to determine if the statement is true or not true.

11. You do- Answer the HOTQ and equations in Journal and tell if statement is true or not true.
Compare equations to determine if the statement is true or not true.
33 – 10 = =
96 – 13 =
56 – 23 =

12. Exit Ticket
Turn to shoulder partner and describe how you can tell if an equation is true or not true.
Have a discussion about why do we need to be able to tell if equations are true or not true.

13. Rate yourself in your journal and explain why you are that rating
