**MODULE 1: Numbers to 10**

**Kindergarten students start out solidifying the meaning of numbers to 10 with a focus on number values and relationships using fingers, cubes, drawings, 5 groups and the Rekenrek. Students then investigate patterns of "1 more" and "1 less". Because fluency with addition and subtraction within 5 is a Kindergarten goal, addition within 5 is introduced in Module 1.**

KEY CONCEPTS:

*Exactly the same/not exactly the same/ the same but ...

*Sort - group objects according to a particular attribute (ex. color, shape and size)

*Counting "how many" in a set or given group arranged in a linear, array, circular or scattered configuration as shown below:

***Finding "hidden partners"**

Example breaking down 5 into two groups: 3 and 2

3 and 2 are the hidden partners

*Number sentence (3=2+1)

* 5 group

*1 more (one more than 4 is 5)

*1 less (one less than 4 is 3)

TOOLS USED:

__Number path 1-10__: a pictorial representation of numbers and number order. Each space is a visual representation of one number, one space, and each number being equal in size. The color change at 5 helps to reinforce the the concepts of 5 and 10.__Rekenenrek__: A Rekenrek is simpy a counting tool with beads like an abacus. The Rekenrek has a 5 and 10 structure with a color change at 5. The 20 bead Rekenrek consists of 2 rows of 10 beads, allowing students to see numbers to 10 as a number line in one row or a ten-frame (5 beads on two rows)__Ten-Frame__: A ten-frame is a 2 by 5 grid (array) used to develop understandings of concepts such as 5 patterns and combinations of numbers to 10.
