- Product Description

This resource with missing addends includes four pages of numbered cards in color with a total of 20 cards. Each numbered card has a number bond with one missing addend.

Teachers should copy the cards on cardstock (for durability and saving for future years) or plain paper, laminate (if desired), cut apart, and then post the cards around the room. If you don't want students walking around the room, the cards can be put in a center such as at a math center or in a pocket chart.

Depending on how many cards you want to use, you can post/use cards number 1-10, cards number 11-20 or all 20 cards at once.

All 20 cards have missing addends with sums 10 to 20.

There are two recording sheets. One is for cards numbered 1-10, and one is for cards numbered 11-20. Students can complete one or two recording sheets when in their center depending on how many cards you post.

Students will get a recording sheet with boxes to write 10 numbers or both recording sheets can be stapled together when working on all 20 cards. Students will roam the room to find the numbered cards. After finding a card, the student will look at the number on the card, find the matching number on their recording sheet, and write the number (numeral) to complete the number bond (missing addend).

Example:

Card number one has the whole number 20 with addend 15 and the other addend is missing, so students will write the number (numeral) 5 on their recording sheet in the number one box because 5 completes the number bond showing that 5 and 15 make 20.

Answer keys are provided for the recording sheets either as a self-check for students or for the teacher to have an answer key to quickly check papers.

***There are 8 total pages including two answer keys: 4 card pages, 2 recording sheets, and 2 answer keys to the recording sheets.

The PREVIEW shows every page included.

This activity is great for a math center.

I hope your students have fun with this "Write the Room" activity for number bonds.

CCSS1.OA.D.8

Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = ▯ - 3, 6 + 6 = ▯.

CCSS1.OA.C.6

Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).

CCSSK.OA.A.5

Fluently add and subtract within 5.

CCSSK.OA.A.3

Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).

CCSSK.OA.A.1

Represent addition and subtraction with objects, fingers, mental images, drawings, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.
