Class Activity Page 157
 
6. Procedures/Methods-

A. Introduction-

1.Start by reviewing finding a new ten and a new hundred using a smart notebook.
2.Explain that we can use several different ways to solve two digit addition problems. We can use the sticks and find the new ten or we can also use the Show All Totals method.
 

B. Development-

1.Use problem in notebook to model the Show All Totals method
2.Students will use mathboards and work along to solve the problem.
 

C. Practice-

1.We work problem 1, 2 and 3 together on the math boards
2.The students will show their boards to me to so I can assess their understanding and concept knowledge.
3.Have student leaders come up and work on each step of the Show All Totals method.
4. Discuss the advantages for using the Show All Totals method. Show them a non example with numbers in the wrong spot.
5.Present the addition problems in expanded form.
 

D. Independent Practice-

Students will get into groups and solve several problems together on butcher paper. They may choose the method that works best for them to solve the problems.
 

F. Checking for understanding-

Student groups will come up and share how they solved their addition problem.
 

G. Closure-

1.Review the reason why we learn different methods of solving addition problems.
2.Will every two digit addition problems have a new ten or a new hundred? Why or why not?
