Lesson 3.4 Break Apart to Add MAFS.2.NBT.2.5 (DOK 1)

Learning Goal  The students will use strategies for adding numbers within 100.

Objective  Students will be able fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

Scale  3- I can, with no help, fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.  2- I can, with limited help, fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.  1- I need a lot of help to add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.  0- I can’t, even with help, add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

Solve & Share  Monica has 24 crayons. Paul has 64 crayons. How many crayons do they have in all?  Solve any way you choose explain your work. +=2464 Crayons

H.O.T. to consider during the lesson  1. How can understanding place value help you solve problems?  2. Use a place value chart to help organize and solve the equation.

Turn to page 142  Follow along as I read the Visual Learning Bridge.  Let’s look at problem 1 & 2 and use the break apart method to solve the equations.  = TenOnes *How can understanding place value help you solve problems? * Use a place value chart to help organize and solve the equation.

Question 2  = *How can understanding place value help you solve problems? *Use a place value chart to help organize and solve the equation. Ones Ten

Objective reminder  Students will be able fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.

Kagan Structure- Think Pair Share  Partner A- shortest or shorter hair answer Questions 3, 5, and 7.  Partner B- shortest or shorter hair answer Question 4, 6, and 8.  Remember to use accountable talk and listening skills.

You do  Work question 10 by yourself.

Exit Ticket- write in journal  13. Cindy has 15 more toy planes than Julie. Julie has 12 toy planes. How many toy planes does Cindy have? (Remember to use C.U.B.E.S. strategy to help create equation)  Use the above question to answer H.O.T.S  1. How can understanding place value help you solve problems?  2. Use a place value chart to help organize and solve the equation.

Rate yourself and explain why you are that rating  3- I can, with no help, fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.  2- I can, with limited help, fluently add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.  1- I need a lot of help to add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.  0- I can’t, even with help, add and subtract within 100 using strategies based on place value, properties of operations, and/or the relationship between addition and subtraction.
