TEKS: (7) Algebraic reasoning. The student applies mathematical process standards to identify and apply number patterns within properties of numbers and operations in order to describe relationships. The student is expected to: (C) represent and solve addition and subtraction word problems where unknowns may be any one of the terms in the problem.
Concept: identify and solve word problems that have missing numerical information. (TEKS 2.7.C)
Objective: Students will be introduced to the concept of missing numbers in addition problems. They will develop different methods they can use to solve for these missing numbers. Students will learn how to solve for missing numbers in addition problems using manipulative.

technology activity
Students will use websites in Math Center reinforcing objective taught, to help students have a better understanding of the concept being taught. Students will use Ipad, to log on to application, that is for number sequence problems, and find the missing number that needs to be found.
Using SuccessMaker program, and customize to target number sequence problems only.
