Math Fact Sorting
Objective: SWBAT identify all of the equal number sentences that match a given answer.
Big Idea: Students work to solve multiple 3 part number sentences and determine if they are equal or not! Students practice using less than, equal to and greater than language!
Print Lesson
Student Cooperative Play
During this part of the lesson, students will play a game in small groups. Common Core emphasizes that students should work collaboratively-this is a college ready skill that students can practice from Kindergarten.
Game Rules:
- Students sit in groups of 4.
- Each person gets 1 card, each card has a different number sentence on it.
- Each student solves their own equation. Then they sort their cards into groups: Less than 15, Equal to 15, Greater than 15
- When students are done with their first card, they draw another card from the pile.
- When a group runs out of cards, each group member will choose a card to "check". They will assess that person's work and make sure they agree with the answer and where it goes.
Game Time: See this video for how this looks in action!
I'll give students 7-10 minutes of game time.

I included header cards so each group knows where to put their groups.
Independent Practice
Directions: Students sort the number sentences into 3 groups. They are deciding which number sentences are equal to each other.
Intervention: Students will use cubes to help them solve these number sentences. Students will use the math fact sort available for free from K-5 Math Teaching Resources. These students will determine if number sentences are less than 10, equal to 10, or greater than 10.
Right on Track: Students will do 3 addend number sentences with sums to 20. Students are deciding if number sentences are less than, equal to or greater than 15.
Extension: Students use a different sort. They determine if a number sentence is less than 50, equal to 50 or greater than 50. See Student Extension Work Example!
I happened to walk by when 2 students in the extension group were discussing whether or not one student's answer was correct! Watch this video of the discussion-this aligns to CCSS MP3, Construct viable arguments and critique the reasoning of others. You see that Jakarin realizes his mistake and can actually explain what misconception he had that led to his mistake!
I'll have students record their thinking on the attached Fact Sort Recording sheet.docx
The Equality Sorts and Number Facts Sort are also attached;
They include the cards for students to sort!
