First Grade Common Core Worksheets 1.OA.7 Understand the Meaning of the Equal Sign
The following attachment is one week of math worksheets, including a quiz for Friday. Each day is designed to be copied front and back; the front page is the focus standard of the week and the back page is review of the previously taught concepts. This week has been designed to fit into the third nine weeks of the yearly progression, but could be used any time after you have taught the review concepts. You could also use the front of the sheets in isolation and use the review pages later, after you have covered those objectives.
The focus concept this week is:
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.
The review concepts this week are:
CCSS.Math.Content.1.OA.A.1 Use addition and subtraction within 20 to solve word problems involving situations of adding to, taking from, putting together, taking apart, and comparing, with unknowns in all positions, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.1
CCSS.Math.Content.1.NBT.C.5 Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used.
CCSS.Math.Content.1.NBT.A.1 Count to 120, starting at any number less than 120. In this range, read and write numerals and represent a number of objects with a written numeral.
Do you need more practice with this objective? I have another week of worksheets that focuses on this standard and it is also in my 1st Nine Weeks Bundled packet.
