In this lesson students will be looking at story problems and then analyzing whether the story is talking about equal groups or unequal groups. Students will need to be able to look at a visual representation of equal groups and write about what they see.
Students are often taught the difference between addition and multiplication is the symbol (+, x) between the addends or the factors. In this lesson students will be looking at story problems and then analyzing whether the story is talking about equal groups or unequal groups. Students will need to be able to look at a visual representation of equal groups and write about what they see.
1. Become mathematical problem solvers.
2. Make mathematical connections.
Invitation to Learn
Pass out chenille stems and beads. Students need to put 11 beads on their chenille stem. After the beads are on the chenille stem, bend the ends up slightly (make a right angle) to prevent the beads from coming off.
As the teacher reads 12 Ways to Get to 11, by Eve Merriam, the students listen to the words and move their beads from one end of the chenille stem to the other, based on the numbers that the book provides.
After reading the story, see if they can ever slide the beads over in an equal group. Share solutions or strategies and have students discuss their reasoning.
Curriculum Extensions/Adaptations/ Integration
These items can be labeled with multiplication sentence or repeated addition sentence.

Students need a solid grasp of mathematical concepts in order to function successfully in an ever-changing world. To facilitate this, educators must provide opportunities for students to deepen their understanding of mathematics. We can accomplish this by engaging students in exploring mathematical ideas and concepts through writing. When students write about mathematics, they think about abstract ideas in a more meaningful way and make connections between what they already know and what they are learning.
