# Utilizing Games and Activities to Strengthen Number Sense

10 minutes to read; time to implement varies

## Description

People who struggle with math often have not had the opportunity to build a strong sense of number.  By working with different components of number sense, and making connections between them, learners can improve their number sense and overall problem-solving skills.

### Anticipated Outcome

Viewers will gain a better understanding of the different components of number sense and some activities and games to use with learners to aid in the development of number sense.

### Components of Number Sense A graphic that represents the components of number sense as a wheel.

The Components of Number Sense wheel comes from our Foundations of Math course.  It was designed to help educators see the big ideas of math, and when utilized as the building blocks of each lesson can offer a more meaningful opportunity to develop number sense.

The components are separated below to allow the reader the opportunity to understand each individual component and how to focus on it with different activities. It is, however, important to note that making connections between multiple components within one lesson or activity is what creates a more robust learning opportunity for the students.  They are not meant to be taught in isolation but developed cohesively within each lesson throughout all grade levels.

The Components of Number Sense include:

• Quantity and Magnitude
• Numeration
• Equality
• Base Ten
• Form of a Number
• Proportional Reasoning
• Algebraic and Geometric Thinking

The Use of Language

Language sits in the middle of the wheel.  Meaningful mathematical discussions provide learners opportunities to build a rich math vocabulary as well as make connections to multiple components of number sense.

### How Do I Strengthen Understanding of Quantity and Magnitude?

Quantity means how many or how much of something there is.

Magnitude means the size of something as it compares to something else.

Some ways to build an understanding of quantity and magnitude include:

• Counting objects
• Count by ones with early learners
• With later learners, count sets of 2, 3, 5, 10, etc.
• Ask “How many” so the learner understands why he/she is counting.
• Comparing quantities
• More/Less
• Shorter/Longer
• Bigger/Smaller
• Recognizing quantities
• 2 tires on a bike; 4 chairs at a table
• 6 petals on a flower, how many petals on 4 flowers?
• Matching quantities shown with different objects
• 3 blocks and 3 crayons
• 7 crackers and 7 dots
• 3 sets of 4 crackers and 2 sets of 6 chips

To emphasize quantity and magnitude, focus on the connection between the amounts of objects and how they compare to other amounts.

The activities listed below can be used to help learners develop quantity and magnitude.

### How Do I Strengthen Understanding of Numeration?

Numeration means naming a given quantity or calculation.

Numbers (the actual amount of something) can be written as words, as numerals with digits, and spoken verbally.  All forms of numeration are important to explain and share with learners.

For early math learners:

• Start with the quantity and spoken language to name it.
• As the learner develops his/her understanding of naming a quantity verbally, then introduce the digit(s).

To emphasize numeration, focus on the connection between the names of the amounts and the actual amounts.

The activities listed below can be used to help learners develop numeration.

### How Do I Strengthen Understanding of Equality?

Equality means having the same value.

Some ways to build an understanding of equality include:

• Counting sets of different objects (e.g., blocks and crayons) to see if they are equal or unequal amounts
• Looking at different ways to separate sets of objects that show the same amount
• 5 red blocks is equal to 3 blue blocks and 2 yellow blocks
• 4 cups of 6 crackers is equal to 2 cups of 12 crackers
• Working with different measurements that show equal amounts
• a half cup of water equals two quarter cups
• 12 one-inch strips of yarn is equal to one foot of yarn

To emphasize equality, focus on the connection between how two or more amounts show the same value.

The activities listed below can be used to help learners develop equality.

### How Do I Strengthen Understanding of Base Ten?

Base Ten is the name of the counting system we use.  It is called base ten because it uses ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9) to show any value.

Some ways to build an understanding of base ten includes:

• Count objects and group them into sets of ten.
• Use ten frames to develop the understanding of filling a base of ten.
• Explore different values using base ten blocks (blocks that show single units, units of ten, and units of a hundred)
• Write numbers in digit form using a place value mat.
• Explore expanded form
• Did you know that other number systems exist?  Explore other bases to deepen the understanding of a base number system.

To emphasize base ten, focus on the making/composing of a full base of ten.  If working with another base, make connections to filling a base of that amount.

The activities listed below can be used to help learners develop an understanding of base ten.

### How Do I Strengthen Understanding of Form of a Number?

Form of a number means numbers can be written in different ways (for example, 25 can also be written as 20 + 5; 15 + 10; 30 – 5; 5 x 5; 100 ÷ 4; etc.).

Being able to write numbers in different ways can make problem-solving easier because the learner can use numbers that are easier to work with or numbers that they understand better.

Some ways to build an understanding of form of a number include:

• Put a set number of beads on a string and leave enough room to move the beads along the string. Separate the beads in different ways and record the ideas.  For example:
• 10 can be 2 beads and 8 beads, or 6 beads and 4 beads
• 12 can be 6 beads and 6 beads, or 9 beads and 3 beads
• Choose a number and think of all the ways you can break the number down into smaller parts and still have the amount you started with. For example:
• 18 = 9 + 9; 18 = 10 + 5 + 3
• 25 = 20 + 5; 18 + 7; 30 - 5; 5 x 5
• Work with money to create different ways to pay for something using different bills and/or coins.
• Brainstorm ways to write fractions or mixed numbers in different ways.
• Explore the conversion of fractions to decimals and record them on a number line.

To emphasize form of a number, focus on the ability to show the same quantities in different ways.

The activities listed below can be used to help learners develop an understanding of form of a number.

### How Do I Strengthen Proportional Reasoning?

Proportional reasoning is the ability to see a relationship between two quantities using multiplication.

There are many ways to see relationships between quantities.  The key to proportional reasoning is that the relationship involves multiplication (and not addition).

Example: For every apple tree, I picked 2 apples.

• In this case, the two quantities are the number of trees and the number of apples.
• The proportional relationship is “times 2” or “multiply by 2” because I can multiply the number of trees by 2 to figure out how many apples I picked.

Non-example: I picked two apples off of each tree.

• I have 2 apples, plus 2 apples, plus 2 apples, and on and on.
• In this non-example, the relationship is “plus 2” because we are adding 2 each time.  We are not multiplying.

Proportional reasoning is critical because learners will encounter many relationships that involve multiplication in real-life problems and advanced math courses.

Some ways to build an understanding of proportional reasoning include:

• Play a copycat game using proportions. For every one jumping jack I do, you have to do three.
• Build with blocks and set a rate such as for every one red block, I have to use two blue blocks. How many blue blocks will I use if I have 3 red?
• Create art pieces on grid paper with proportions. For example, for every square I color yellow, I have to color 5 squares purple. How many purple squares will I need with 3 yellow?
• Make a scale drawing of your room with a proportion (for example, every inch in my drawing will represent 12 inches in my room).

To emphasize proportional reasoning, focus on the relationship between numbers using multiplication.

The activities listed below can be used to help learners develop proportional reasoning.

### How Do I Strengthen Algebraic and Geometric Thinking?

Algebraic thinking includes recognizing patterns and using numerical relationships to understand real-world scenarios and how things change.

Geometric thinking involves understanding the size, shape, position, and dimensions of things.

Some ways to strengthen algebraic and geometric thinking include:

• Finding shapes in a picture hunt
• Create patterns with different objects
• Sorting figures into categories (number of sides, number of points, straight/curved lines, interior angle measures, etc.)
• Play with tangrams and create figures using different shapes
• Creating graphs and charts and discuss the patterns and relationships they show using numerical values from real-world scenarios
• Figuring out unknown quantities like “There are 8 eggs in a carton that holds 12 eggs, how many eggs were taken out?”

To emphasize algebraic and geometric thinking, focus on the patterns and spatial relationships that help to explain what happens in the real world.

The activities listed below can be used to help learners develop algebraic and geometric thinking.
