In this unit, children have experiences that solidify their understanding of one-to-one correspondence and the cardinal principle when counting sets. The following big ideas will be covered in this unit:
- Numbers are related to each other through a variety of relationships. For example 6 is one more than five and is four less than 10.
- Each successive number refers to a quantity that is exactly one larger.
- Quantities can be compared using words such as, one more, one less, and two more, two less.
- Written numerals are symbols that represent quantities and number words. (within 10)
- Shapes can be described in terms of their location.
- Shapes can be moved or rotated without changing the shape’s properties.
- Direct comparisons are made when objects are put next to each other and the ends are lined up.

K.CC.A. Know number names and the count sequence. K.CC.A.1. Count to 100 by ones and by tens. K.CC.A.2. Count forward beginning from a given number within the known sequence (instead of having to begin at 1). K.CC.A.3. Write numbers from 0 to 20. Represent a number of objects with a written numeral 0-20 (with 0 representing a count of no objects). K.CC.B. Count to tell the number of objects. K.CC.B.4. Understand the relationship between numbers and quantities; connect counting to cardinality. K.CC.B.4a. When counting objects, say the number names in the standard order, pairing each object with one and only one number name and each number name with one and only one object. K.CC.B.4b. Understand that the last number name said tells the number of objects counted. The number of objects is the same regardless of their arrangement or the order in which they were counted. K.CC.B.4c. Understand that each successive number name refers to a quantity that is one larger. K.CC.B.5. Count to answer “how many?” questions about as many as 20 things arranged in a line, a rectangular array, or a circle, or as many as 10 things in a scattered configuration; given a number from 1–20, count out that many objects. K.CC.C.6. Identify whether the number of objects in one group is greater than, less than, or equal to the number of objects in another group, e.g., by using matching and counting strategies. K.CC.C.7. Compare two numbers between 1 and 10 presented as written numerals. Operations & Algebraic Thinking K.OA.A. Understand addition as putting together and adding to, and understand subtraction as taking apart and taking from.
Drawings need not show details, but should show the mathematics in the problem. (This applies wherever drawings are mentioned in the Standards.) K.OA.A.2. Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem. K.MD.A. Describe and compare measurable attributes. K.MD.A.1. Describe measurable attributes of objects, such as length or weight. Describe several measurable attributes of a single object.
For example, directly compare the heights of two children and describe one child as taller/shorter. K.MD.B. Classify objects and count the number of objects in each category.
Limit category counts to be less than or equal to 10. K.G.A. Identify and describe shapes (squares, circles, triangles, rectangles, hexagons, cubes, cones, cylinders, and spheres). K.G.A.1. Describe objects in the environment using names of shapes, and describe the relative positions of these objects using terms such as above, below, beside, in front of, behind, and next to.

Students will have opportunities to:
- Create mathematical representations using numbers, words, pictures, symbols, gestures, tables, graphs, and concrete objects (MP.2)
- Make sense of the representations they and others use (MP.2)
- Make connections between representations (MP.2)

- Counting tells how many things are in a set.
- When counting a set of objects, the last word in the counting sequence names the quantity for that set.
- Each object being counted must be given one count and only one count.
- A number can be represented by a set of objects, then by a word, and finally by a numeral.
- All numbers can be composed and decomposed.
- Numbers can be compared using words such as, more, less, and fewer.
- Shapes have sides and angles, which can be counted and compared.
- Triangles, rectangles, squares and circles can be defined based on their attributes.
- Ten-frame can be used to represent numbers.
|
- Written numerals are symbols that represent quantities and number words. (within 20)
- Written numerals can be compared using words such as, one more, one less, and two more, two less.
- Some shapes are flat (2-D) while other shapes are solid (3-D).
- If an object is moved, its length does not change.
- Tools, such as cubes and a balance can be used to measure length and weight.

| The following lesson plan sequence is obtained from Everyday Mathematics 4. Each lesson is aligned with a learning objective to inform the teachers on what students should be able to at the end of the lesson. The student objective informs the students of their learning goals for the day and it should be reviewed before, during and at the end of the lesson. Each lesson includes a mathematics task that should be implemented to meet the learning objectives. Teachers can select from the practice opportunities to reinforce the learning goals of the day. |

| The following language supports are for English Language Learners but could also be used to support any struggling learner in mathematics. The strategies are obtained from the SIOP model. The language objectives will support students' academic language development. The sentence stems and starters provides the support many students need to be able to participate in discussions and writing about mathematics. |
