Title: Domino Grab
Day One: Content Development / Grade Level:
K-1 / Resources for Lesson:
High Yield Routines:
Origo Fundamentals:Yellow Level
Lesson: In this game, students practice the quick addition of two quantities less than seven, building on their ability to recognize dots. / Guiding (Focus) Question:
How can dominoes help with mental addition of smaller amounts within a whole group?
Unit Learning Targets: Students will learn mental strategies for addition by learning the skill of subitizing, by working with dominoes.
Success Criteria: I can practice mental addition strategies of two quantities less than seven and share my answer with my partner.
Mathematical Practices
  1. Make sense of problems and persevere in solving them.
  2. Reason abstractly and quantitatively.
  3. Construct viable arguments and critique the reasoning of others.
  4. Model with mathematics
  5. Use appropriate tools strategically.
  6. Attend to precision.
  7. Look for and make use of structure.
  8. Look for and express regularity in repeated reasoning.

I can use mental strategies (subitizing) to add two quantities less than 7. / Language Objectives:I can verbalize the total number of dots on the domino to my partner
(Throughout unit make sure all four language modalities, reading, writing, speaking and listening are addressed)

Instead of having pairs grab for the pile, each person turns over one card and calculates the total dots on his/her own card. If a student has the same total as the last card laid down they keep the cards in the stack. / Materials:
  • 4 copies of page 38, 39 to make one set
  • Real dominoes could also be used

Student Engagement: Leadership
How will this lesson develop leadership skills for our migrant students?
2. I speak and listen well to others. / Strategies to develop leadership skills:
Warm Up: (10 Minutes) High Yield Routines
  1. Use a few of the “Quick Images” examples from the book. Different dot pattern arrangements, where students quickly decide how many dots they saw and discuss how they knew.

Content Development: (10 Minutes)
  1. Now, Flash one of the domino cards and ask students to quickly call out the number of dots they see. As students get quicker, reduce the amount of time you show the card.
  2. Ask for volunteer to select one domino card and have the students give a thumbs up when they have the total dot. Invite students to share their strategies on how they found the total.
  3. Next, tell students the total number of dots on a domino and have them decide the number of dots on each side. (EX the total is seven, students could say 4 and 3 or 5 and 2)
/ Notes:
Real dominoes could work better, and possibly to use as an extension. These dominoes do not have more than 6 dots on a side.
Game Activity: (30 Minutes)
  1. Observe students as they play the game. The game could be changed where speed is not important and there is no “grabbing” Students could take turns flipping over a domino and calculating the total. If a student lays down a domino with the same total as the last domino, that student would keep all the dominoes in the pile. Play would continue and the student with the most domino cards is the winner.
  2. Ask students to verbalize how they “see” the total as they are playing. (I saw 5 and 4. I know 5 plus 5 is 10 so 5 plus 4 must be 9)

Reflection: (10 Minutes)
  1. Flash a few of the domino cards and ask students to explain their strategies for calculating the totals.
  2. Discuss mental strategies for addition and visualization skills.
/ Review and Assessment:
An extension to this activity is pairs could play go fish using the domino cards. Each pair is dealt five domino cards and they play the game like “Go Fish” The winner is the player to have no remaining cards or the most matched pairs at the end.
Home School Connection
  1. Ask your family to “flash” dominoes for you to see and tell your family you will tell them the number of dots without counting each dot. Write about or draw some of the dominoes you practiced with.

Domino Addition/Dice Addition 2

Day Two: Problem Solving

Title: Domino Addition/Dice Addition 2

K-1 / Resources for Lesson:
High Yield Routines:
Illustrative Mathematics: Domino Addition/Dice Addition 2
Lesson: This task will help students understand the commutative property of addition. This lesson reinforces that addends can be written in any order. / Guiding (Focus) Question:
Is the total number of dots the same regardless how a domino is oriented?
Unit Learning Targets: I can represent my dominos by writing addition equations to match my dominoes. I can write multiple equations for the same domino.
Success Criteria: I can classify my dominoes by their sums, and represent a new sum after rotating the domino.
Mathematical Practices
  1. Make sense of problems and persevere in solving them.
  2. Reason abstractly and quantitatively.
  3. Construct viable arguments and critique the reasoning of others.
  4. Model with mathematics

The use of real dominoes and either a document camera or pocket chart for the dominoes to help ELL students. / Materials:
Domino Addition (task)
Dominoes (1 set per pair)
Paper
Pencils
Could also do the task titled “Dice Addition 2” instead of using dominoes it uses a standard dice.
Student Engagement: Leadership
How will this lesson develop leadership skills for our migrant students?
4. I use what I have learned. / Strategies to develop leadership skills:
Warm Up: (10 Minutes) High Yield Routines
Number of the Day-Practice a few numbers that are less than 10
  1. Discuss number combinations for that number
  2. Odd or even
  3. Discuss with students if 4+3 is the same as 3+4

Content Development: (10 Minutes)
  1. Ask a student to pull a domino from the bag and students practice calling out altogether how many dots total.
  2. Count the number of dots together to check the mental math.
  3. Ask students to name an addition equation for the domino. Next rotate the same domino and write another addition equation.
/ Notes:
An easier version and task for students is the task titled “Dice Addition.” Students are just working with a standard dice instead of dominoes
Problem Solving Activity:
  1. In pairs students can practice drawing dominoes (these dominoes will have larger sums than the game activity had) drawing the dot patterns and recording the two addition equations.
  2. Pairs can also look for dominoes that have a particular sum, and draw all the related dot patterns and equations.

Reflection:
  1. Have students share drawings and some the equations they wrote.
  2. Discuss and review the focus question and decide if rotating the domino and changing the number sentence changes the answer.
  3. Example 4+3=7, 3+4=7
/ Review and Assessment:
Home School Connection
  1. If a set of dominoes can be provided for students, have students practice the games with their families. Encourage students to practice mental strategies and share with their family how each domino can have two different addition equations.
