Add It Up! Exploring Addition with Fun Manipulatives Lesson Plan

This 1st-grade math lesson focuses on introducing students to the concept of addition using manipulatives. The lesson begins with a review of counting to reinforce number recognition. It then demonstrates how to add simple numbers by physically combining counting objects, allowing students to visually and tangibly grasp the idea of putting numbers together.

Students participate in guided practice, working in small groups to solve addition problems using manipulatives while gaining support and feedback. Following group work, students engage in independent practice using whiteboards to record their answers, reinforcing their understanding.

The lesson concludes with a discussion to review what students learned, fostering an environment of sharing and celebration, with students receiving stickers for their efforts. Assessment is conducted through observation and review of student work, ensuring that each child's understanding is monitored. The lesson accommodates diverse learning needs with differentiated support for students who require it while providing challenges for advanced learners. Overall, this interactive approach promotes a solid foundation in addition through hands-on experiences.

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

Solve word problems that call for addition of three whole numbers whose sum is less than or equal to 20, e.g., by using objects, drawings, and equations with a symbol for the unknown number to represent the problem.

Apply properties of operations as strategies to add and subtract.2 Examples: If 8 + 3 = 11 is known, then 3 + 8 = 11 is also known. (Commutative property of addition.) To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)

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).
