Product Description
Directions:

This unit contains 5 number bond centers to use with your students. I usually take 2 weeks for this center. On week 1 I follow the guidelines below. For week 2, I put all 5 centers out and rotate the students around to each of them. Then I can walk around and see who will need additional help, and which students understand each of the aspects I am trying to teach.

Day 1, Introduction – Giant Number Bond Flowers (Anchor chart included)
This center should be cut out and put together and given to each student to help them understand the concept of number bonding with your students. I begin by writing a number between 2 and 12 in my big flower on the laminated anchor chart using a dry erase marker. Student then count out the correct number of seeds and place them in the big flower on their number bond. After they count out the correct number of seeds they can distribute them between the smaller two flowers. As they get done I call on a couple of students and get some of the different solutions and write them on my smaller flowers on the anchor chart and then write the addition problems on the side. I do this several times until students are able to complete on their own. They can then use the yellow circles with numbers on them to complete the activity on their own as a center.

Day 2, Practice with new skills – Play Dough Number Bonds
This center should be printed on cardstock and laminated. You may need to print more than one copy so each student can have their own copy or this can be used as a small group activity. Each student will make “seeds” from play dough (alternatively they can use the seeds printed if you don’t want to use play dough) and then place them in the flower pots to match the number on the seed packet. Once students are done with their play dough mat they will record it on the answer sheet and then see if there is another way they can make the number on the seed packet and record that as well. When they cannot find another way they will switch to a new mat and complete the activity again.

Day 3, Take it to the next level – Number Bond Flower Pot Matching
Print on cardstock and laminate. This center is differentiated with 3 different levels. In the beginning the students will put the blank flowers in the numbered flower pots and then put the correct number of “seeds” in each flower. Once students feel comfortable with that they can place 2 flowers in each pot that add up to the number on the flower pot. As students become more familiar they can place matching addition problems into the numbered flower pot.

Day 4, Clothespin Decomposing
Print on cardstock and laminate. This center is differentiated with 2 different levels. For beginners the students will be given unifex cubes or other counters to help them determine which math problem matches the number on the large flowers. As students progress you can take away the counters and let them rely on other means to determine which addition problem matches the number on the flower. Once students have moved beyond that give them the blank cards and let them write down 2 addition problems that match the number on the flower.

Day 5, Find the Missing Addend
Print on cardstock and laminate. Place all cards face down on the table and let students pick a card. Then they will use a dry erase marker to fill in the missing addend that works with the other addend to make the number on the flower pot. I have included a worksheet that can be sent home for homework or be used for morning work. It is blank, print out a copy add your own numbers and make as many copies as needed. Used this way the same sheet can be used numerous times.
