Also, students completed a ‘composing 10 craft’ for the hallway using polka-dot monsters! They were to select two colors and color some one color and the other a different color. This was followed by them writing the corresponding equation that goes with their work.
After mastering the concept of ‘composing’, we learned ‘decomposing’. We discussed how composing is putting two parts together to make a total, but decomposing is taking the total and breaking it into two groups. We brought movement into this concept. They stood in a line on the carpet and once I said 3,2,1 “decompose” they were to break into two groups on two different rugs.
To conclude the week’s learning, we played a game with partners. Students were paired and had to create combinations that add up to ten. We played as many times as it took for each team to get done first. We will present more opportunities for students to practice composing/decomposing 10 next week with number bonds, part-part whole and more active/movement strategies to help them fully grasp the conceptual understanding.
