Objectives

Student will begin to understand two-digit addition computation.

Subjects
Math

#### 1 Hook

Activity: Conversing

Ask students if they have ever played with dominos before. Talk to them about how now they can use dominos to learn how to do addition with two-digit numbers!

#### 2 Direct Instruction

Activity: Presenting

*Break up students into groups of 2-3. Give each group a set of dominos and have them turn the dominos horizontally in order for them to see a two-digit number (3 dots on the left and 4 dots on the right=34).

*Once students start to see a connection in the place value of dominos, have them take two dominos and add them together.

*After they are comfortable with this, give them the hand-out with dominos that have missing dots. Have students fill this sheet out individually.

#### 3 Guided Practice

Activity: Exploring

*Do an example with the students using 2 random dominos.

*Go through the process of adding up each side of the dominos.

*Then draw a set of dominos on the board with a side missing, but give students the answer.

*do a couple of examples and then let them get into their own groups and make up their own problems

#### 4 Independent Practice

Activity: Investigating

*Have students work on a worksheet that you have created with dominos that have missing dots.

*they are allowed to use the dominos as manipulatives

#### 5 Wrap-Up

Activity: Conversing

*so today we have learned how to add two-digit numbers.

*now before you move on, do a two-digit problem on the board without using the domino template
