Understanding how to determine whether two addition equations are equal or not is a foundational math skill in first grade. This interactive lesson introduces students to the concept of "equal" and "not equal" using number sentences within 20. With colorful visuals, clear instructions, and engaging examples, learners practice evaluating whether two math statements have the same total. This skill is not only essential for building number sense, but also lays the groundwork for algebraic thinking later on. Through online learning, first graders develop confidence as they reinforce the concept of mathematical equality in a fun and supportive environment.
In everyday life, the idea of things being equal or not equal comes up more often than you might think. From comparing prices at the store to balancing two sides of a recipe, students who grasp this early math concept are better prepared to apply it in real-world situations. That’s why interactive lessons like this one are so valuable. As part of a complete elementary teaching toolkit, this educational game-style activity gives students meaningful skill practice that supports what they are already learning in the classroom. It’s ideal for supplementing math instruction during classwork or homework time.
Teachers and parents alike can use this interactive resource to strengthen first grade math skills through targeted online learning. The digital format makes it easy to assign this lesson for independent practice, whether at home or in school. It also fits seamlessly into math centers, small group work, or even remediation sessions. As students work through equal and not equal problems in a playful, game-like setting, they receive immediate feedback, which encourages growth and boosts mastery. For educators looking to enhance their math curriculum with high-quality digital tools, this 1st grade lesson on equal and not equal equations within 20 is a perfect fit.
This interactive math lesson is categorized as Level A. It may be best suited for 1st grade students.

Operations And Algebraic Thinking
Add And Subtract Within 20.
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).
Adding Multiples of 10 (to 100) (Level A)
