## Description

Here is a challenging and fun way to practice several math facts skills. Each of these 32 balance the equation task cards features two equal equations with one missing number. The equations are a mix of addition and subtraction within 10. The missing number appears equally in each of the four positions.

Answer key, student answer sheet, and a cover card are also included. In addition, there is also a card for students to create their own equations. These cards would work well for use at math centers, as test prep, or with the whole class in a game such as scoot.

You may want to have your students use manipulatives in conjunction with these cards.

Printing and Cutting:

These cards were made to be printed in color, but will print out fine in gray scale too. They should print out with even margins around the cards; however, because every printer is different, it is possible that you may need to adjust your printer settings. Selecting “actual size” or adjusting the size percentage should do the trick. Cut the cards apart using the dotted guidelines (discarding the bottom strip). Laminate if possible. Another option is to print on cardstock.

Common Core Standards Addressed

Kindergarten

CCSS.Math.Content.K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings1, sounds (e.g., claps), acting out situations, verbal explanations, expressions, or equations.

CCSS.Math.Content.K.OA.A.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

CCSS.Math.Content.K.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).

CCSS.Math.Content.K.OA.A.4 For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.

CCSS.Math.Content.K.OA.A.5 Fluently add and subtract within 5.

Grade 1:

CCSS.Math.Content.1.OA.B.4 Understand subtraction as an unknown-addend problem. For example, subtract 10 – 8 by finding the number that makes 10 when added to 8.

CCSS.Math.Content.1.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).

CCSS.Math.Content.1.OA.D.7 Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.

Grade 2:

CCSS.Math.Content.2.OA.B.2 Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.
