This packet is designed to help students build fluency with addition and subtraction facts while also mastering CCSS 1.OA.D.7: Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false.
First grade students need scaffolded experiences to develop this skill. This pack includes 240 equation cards that can be used for sorting activities and/or for Scoot games. The cards are presented in 10 levels of increasing complexity.
To aid with organization, each set of cards is presented on a different black and white background. Each level includes 24 true/false equation cards and an answer key with the same background as the cards. The Scoot recording sheet for student use is also included, along with one True/False sorting mat.
Click on preview to take a look at the format of the student recording sheet, a sample answer sheet, and some more equation cards.
The Scoot Games and Levels for Sorting Activities are:
Addition within 10
Subtraction within 10
Mixed +/- within 10
Addition within 20
Subtraction within 20
Mixed +/- within 20
Addition Problems such as 5 + 1 = 4 + 2 within 10
Subtraction Problems such as 6 - 1 = 7 - 3 within 10
Mixed +/- Problems such as 8 - 2 = 5 + 4 within 10
Mixed +/- Problems such as with 5 + 3 = 14 - 5 within 20
For sorting activities, I have kids work with partners to sort a set of cards into 2 piles: True and False. Kids take turns choosing a card and telling their partner whether they think the equation is true or false and why. If the two partners do not agree right away, they explain their thinking and reasoning to one another. If needed, they can also “prove it” using manipulatives.
When I first made the equation cards, something just bothered me. I realized I was really concerned about having a child pick a card up and “believe” the equation, maybe even learn a math fact incorrectly. So, I added “True or False?” to each card. After that, I felt so much better!
I hope you find this packet helpful! : ) Anne Gardner, Common Core Connection
