Kindergarten Mathematics Module 1, Topic H

children learning

Topic H is a mirror image of Topic G. Students explored one more in Topic H and will explore one less in Topic G. In Lesson 33, the students use their knowledge of relationships between numbers to order quantities of objects on paper (dot cards, picture cards, and shapes) from 10 to 1 and then match 1–10 digit cards to each set of objects in descending order. Lesson 34 extends this concept by helping the students state one less than a given number. “9 triangles is one less than 10 circles, 8 squares is one less than 9 triangles, etc.” Lesson 35 again helps children to kinesethtically internalize the concept of one less by building linking cube stairs, but this time instead of starting at the bottom on the first cube, there is a “princess in a tower who walks down the stairs starting at the top 10-cube stair.” The children discuss what is happening as the princess walks down each step. From this concrete exercise the students are then asked to arrange, analyze, and draw 1 less configurations other than the stair or tower format. They might be given a group of objects to count on paper in a scattered or circular formation and then asked to cross out 1 object from the group and count again. To conclude this module, the students are given a culminating task which calls on the students to use what they have learned to complete a series of tasks.
