## GEOMETRY

### What your child will learn

 Describe objects in the environment using names of shapes, and tell positions of these objects usingterms such as above, below, beside, in front of, behind, and next to. (K.G.1) Quarter 1 and 4 Correctly name shapes regardless of their size or orientation. (K.G.2) Identify shapes as two-dimensional (lying in a plane, “flat”) or three- dimensional (“solid”). (K.G.3) Compare two- and three-dimensional shapes describing their similarities, differences,parts (e.g., number of sides and vertices/“corners”) (K.G.4) Model shapes in the world by building and drawing shapes. (K.G.5) Put together simple shapes to form larger shapes. (K.G.6) Quarter 1 and 4 Quarter 1 and 4 Quarter 1 and 4 Quarter 1 and 4 Quarter 1 and 4

### Vocabulary

 Two-Dimensional (flat): The outline of a shapesuch as a triangle, square, or rectangle Three-Dimensional (solid): A shape having length, width, and height Face: The flat surface of a solid figure Square: A four-sided shape with equal sides and corners Circle: A flat shape with no sides or corners Hexagon: A shape with six sides Cylinder: A 3-D shape with two circular faces Cone: A 3-D shape with a curved surface and one circular face Side: Line-segments of shapes Rectangle: A four-sided shape with two sets of sides that are equal and parallel, and four right angles Triangle: A three-sided figure Sphere: A solid shape similar to a basketball Cube: A 3-D shape with six square faces

### Activities at home

• Look around your home for solid shapes. Name at least 3 solid shapes.

• Look around your home for flat shapes. Draw at least three of the shapes.

• Look around your home for circles. Count them and record how many you found.

• Use bendy straw, toothpicks, or pipe cleaners to many shapes as you can. Record the names of your shapes.

• Make a picture using 2 circles, 3 triangles, & 1 rectangle. Describe to a friend how you made it.

• Explore Position words. Use toys to model before, after, above, below, and beside. Describe using attributes. Ex. The blue car is behind the red car.

## COUNTING & CARDINALITY

### What your child will learn

 Count to 100 by ones and by tens. (K.CC.1) Count forward starting with any number (instead of having to begin at 1). (K.CC.2) Write numbers from 0 to 20. (K.CC.3) When counting objects, say the number names in order, pairing each object with one and only one number name and each number name with one and only one object. (K.CC.4) 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.4) Understand that each successive number name refers to a quantity that is one larger. (K.CC.4) Count to answer “how many?” (K.CC.5) Identify whether one group of objects is greater than, less than, or equal to the number of objects in another group (K.CC.6) Compare two numbers between 1 and 10 presented as written numerals. (K.CC.7)

### Vocabulary

• One-to-one Correspondence: Students assign one number to each object as they count

• Count On: Starting at a given number and counting forward from that number

• Greater Than: A number that has a higher value than another number

• Less Than: A number that has a lower value than another number

• Equal: Having the same value

### Activities at home

• Play the license plate game with numbers as you walk through your neighborhood. Have them look for a 1 on a license plate. Then find a 2, then a 3, and so on.

• Write your name and a family member’s name. How many letters are in your name? How many are in your family member’s name? Which name has more?

• Look through a store ad. Cut out numbers 0-20. Put the numbers in order from least to greatest.

• Grab a handful of an item, cereal, beans, etc. Estimate how many pieces you grabbed. Now count them. Was your estimate close?

• Estimate how many spoonfuls it take to finish a bowl of cereal. Count each spoonful as you eat.

• Walk around your home. Count how items are plugged into the wall.

• Show the number 5 in as many ways as you can. Use pictures and numbers.

## MEASUREMENT & DATA

### What your child will learn

Describe measurable attributes of objects, such as length or weight. (K.MD.1) Quarter 1, 2, and 3 Compare two objects with common measurable attribute, to see which object has "more of”/“less of” the attribute. For example, directly compare the heights of two children and describe one child as taller/shorter. (K.MD.2) Sort objects into categories; count the numbers of objects in each category. (K.MD.3) Quarter 1, 2, and 3 Quarter 1, 2, and 3

### Vocabulary

Attribute: A characteristic of an object that students use to define the object.Example:Thin, thick, small, large, 3 sides, 4 sides, etc. Length: The distance between two points or objects Weight: A measure of how heavy something is Non-Standard Units of measurement: Any real item that can be used to measure. Sorting: Grouping objects based on similar attributes

### Activities at home

• Trace your foot with chalk outside. Trace a friend’s or family member’s foot too. Which foot is longer?

• Sort a bag of skittles or other candy by color. Count each color. What color has the most? What color has the least?

• Get three different cups. Put them in order from shortest to tallest.

• Sort the mail by name. Who has the least amount of mail? Who has the most amount of mail?

• Find 3 objects in the home that are longer than your shoe.

## NUMB. OPER. IN BASE TEN

### Vocabulary

• Place Value: The value of the place of the digit in the number (For example: in 27, 2 is in the 10's place and is worth 20)

• Compose: Putting numbers together to make a new number (For example: 5+10=15)

• Decompose: Breaking a number apart (For example: 15=8+7)

• Equation: A mathematical statement containing an equal sign, to show that two expressions are equal

• Add: To join two or more numbers

• Subtract: To take one quantity away from another

• Ten: A group of ten ones

### Activities at home

• Use a stick of spaghetti to represent 10 and marshmallows to represent ones. Represent the numbers 12, 13, and 16 with the spaghetti and marshmallows.

• Use a popsicle stick to represent a ten and beans to represent ones. Using a deck of cards, give your child a 10 card, and draw another number card, then add the numbers together and show the number with sticks and beans.

• Walk from one end of the kitchen to the other and count how many steps, then show how many steps were taken with sticks and beans.

## OPERATIONS & ALGEBRAIC

### What your child will learn

 Represent addition and subtraction in many ways. (K.OA.1) Quarter 3 and 4 Solve addition and subtraction word problems within 10 (K.OA.2) Break apart numbers into pairs in more than one way (e.g., 5 = 2 + 3, 5 = 4 + 1, and 5 = 5 + 0). (K.OA.3) Find the number that makes 10 when added to a given number. (e.g., If you have 6 what number is needed to make 10?) (K.OA.4) Fluently add and subtract within 5. (K.OA.5) Quarter 3 and 4 Quarter 3 and 4 Quarter 3 and 4 Quarter 3 and 4

### Vocabulary

Add: To join together two or more numbers Subtract: To take one quantity away from another Equation: A mathematical statement containing an equal sign, to show that two expressions are equal Equal Sign: Having the same amount or value Decompose: To break a number into smaller parts to simplify computation. Example: 15 = 10 + 5. Compose: To put decomposed numbers back together. 10 + 5 = 15

### Activities at home
