3 Overview of Dominoes It is believed dominoes evolved from dice. In fact, the numbers in a standard double-six set of dominoes represent all the rolls of two six-sided die. It is thought they originated in China around the 12 th century. They have been used in a large variety of games for hundreds of years, and today, dominoes are played all over the world. When playing games, children can learn a great deal concerning mathematical concepts and number relationships. Often they are required to use critical thinking skills as well as varied math strategies to solve them. Some of the domino activities in this resource will use games while others will extend, enhance, or introduce a new math concept. For these activities, you may use commercial sets of dominoes or copy the blackline on page 10. It can be copied on cardstock and then cut out. Be sure to copy each set onto different colors of cardstock as this makes it easier to keep the sets together. You should have at least one set of 28 dominoes for every two children. Since children are curious and inquisitive, plus some may have never seen dominoes, allow time for play and exploration before beginning any instruction. This is constructive as well as a productive use of class time. If they are not given this, most children will fool around and investigate during the teaching time. V. Rauch (Scipi),

4 Introduction I am always looking for ways to make ordinary items into manipulatives for the classroom. A couple of years ago, I discovered that many math activities can be created using dominoes. Since a complete set is not expensive, I started exploring all the ways I could use them in a math lesson; hence, the construction of this resource. The following activities and games vary in difficulty; so choose appropriately for your class. Because dominoes can be moved around without the need to erase or cross out an answer, students are more comfortable and willing to try a range of activities. There is something about not having to put a permanent answer on the page that allows the student to explore, investigate, probe, problem solve, and yes, even guess. Objectives: To problem solve using dominoes; to use critical thinking skills; to use dominoes to solve math problems and to practice math facts. Materials Needed: Domino Page (page 10 of handout) Various sets of dominoes of different colors. To purchase sets of dominoes attend yard sales or shop at The Dollar Tree. The size of the domino set depends on the largest number of dots appearing on one side of the domino. A set of dominoes will have anywhere from 28 to 190 pieces; so you can decide which ones you want to use or make for your set. A set of 28 dominoes is needed for the activities in this resource. For Overhead Dominoes: 1) Copy and cut out the 28 dominoes on page 10. 2) Using a paper punch, punch out the black dots on each end of the domino. 3) Laminate for sturdiness. 4) Store each set of dominoes in a snack size plastic bag. Helpful Hints: Construct the class set of dominoes from different colored cardstock. In that way, each student or team can have one specific color, eliminating the problem of everyone having only white or black ones. When a domino is dropped or misplaced, it is easier to discover to whom it belongs based on its color. Label the snack bags for easy storage such as red domino set, green domino set, etc. V.

5 Domino Sort There are various ways a set of dominoes can be sorted. Pair up your students and have them try sorting the dominoes using the following criteria. Sort This Way How many did you find? Write the answers below. Students aren t required to draw the domino; they may simply write the number sentence as shown below. 1) One side is blank ) Doubles ) Even numbers on both sides ) Odd numbers on both sides ) One side is a prime number *One is not a prime number. It is considered a unit! Two is the only even prime number. V. Rauch (Scipi),

6 Four Digit Place Value If you place two dominoes next to each other horizontally a four digit number will be created with a thousands, hundreds, tens, and a ones place. For example, the domino on the right is the number 3,165. Randomly choose two dominoes and place them on the first set of blanks to make a four digit number. Using that number, answer the questions below. Now make a new problem by rearranging the same dominoes for Problem #2. Answer the same questions using the new four digit number. Problem #1 Problem #2 1) Write the number. 1) Write the number. 2) Write the number using words. 2) Write the number using words. 3) What digit is in the: 3) What digit is in the: a) Ten s place a) Ten s place b) Thousand s place b) Thousand s place c) Hundred s place c) Hundred s place 4) Round this number to the: 4) Round this number to the: a) Nearest hundred a) Nearest hundred b) Nearest thousand b) Nearest thousand c) Nearest one c) Nearest one d) Nearest ten d) Nearest ten V.

7 Basic Division Facts Division may be viewed by designating half of the domino as the divisor and the other = half as the dividend. The answer to a division problem is called the quotient. Depending on your preference, the problem may be written in either of the ways seen on the right. Please note how the first 1 2 or problem is set up. This may cause some confusion for your students; so, take the time to explain why it is written that way. Two separate handouts have been created so that you can choose the division method you want your students to use. (pages 19 & 20) Either way is effective, but it is recommended that one or the other be chosen in advance and taught as the model. Do not confuse the student with an either or approach. Because the double six box of dominoes has a limited number of combinations, the double nine dominoes would work best for division. If students want to use a domino such as the sample (red) on the right, it will have to be rotated to look like the one on the left (blue) because in math, we cannot divide by zero. See page 21 for an explanation The Great Divide To practice division facts, play the game on the next page. (NOT available in free version) You will need your dominoes and one die. 1) Turn over all of the dominoes so you cannot see the dots. 2) Choose one domino and add the dots together. This is the total number or dividend. 3) Now, roll a die to see how many groups (the divisor) you must divide or separate that number into. Divisor 4) Solve the problem. Caution: you may have a remainder. 5) Record the problem and the answer in the boxes provided on page 18. To make the game more challenging and to practice all the division facts 2 1) Choose two dominoes and add the dots together. 2) This is your total number or dividend. 3) Roll two dice to see how many groups (the divisor) you must divide or separate that number into. 6 Dividend 2 1 V.

9 Solitaire 12 Number of Players: 1 Materials: One set of double-six dominoes (see page 10) Directions: 1) Place all of the dominoes face down on your desk. 2) Turn over six dominoes so that you can see the dots. 3) Look for any two dominoes that when the dots are added together the sum is =12 4) The two dominoes whose sum is 12 are removed, and two additional dominoes are turned face up. 5) Play continues as you look for two upturned dominoes that equal 12. New dominoes are turned over to replace the paired ones that are removed. 6) When the entire set of dominoes can be paired off into twelves, Solitaire 12 has been solved, and you win! 7) If there comes a point in the game where no two dominoes out of the six will equal 12, you lose the game, but. 8) Try again!
