Florida B.E.S.T. MA.K.AR.2

MA.K.AR.2 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.K.AR.2.1

  Explain why addition or subtraction equations are true using objects or drawings.

01

What Students Need to Do

Students compare the quantities or expressions on both sides of an equal sign. They decide whether both sides have the same value and find missing amounts that make an equation true.

02

What Mastery Looks Like

Students identify whether two sides show the same amount. They can complete equations such as 4 = 1 + __ and explain that the equal sign means both sides match.

03

Common Misconceptions

Students may think the equal sign means “the answer comes next.” They may accept 3 + 2 = 4 or reject 5 = 2 + 3 because of where the total appears.

04

How to Assess It

Give students the prompt: “Circle every true equation: 4 = 4, 2 + 1 = 3, 5 = 3 + 1, 4 = 1 + 3.” Ask them to explain one choice.

1. 01

   Give pairs plastic bears and equation mats, then have them build matching groups on both sides of an equal sign card.

2. 02

   Ask, “Does 5 = 2 + 3 make sense?” and have students draw both sides before explaining their answer.

3. 03

   Play an equation matching game where students pair cards such as 4, 3 + 1, and 2 + 2.

4. 04

   Share six crackers between two plates in different arrangements, then write equations showing when both sides have the same total.
