### Area and Perimeter

Two weeks back I wrapped up my Area and Perimeter unit. Around this time of the year, many schools are working on their Geometry and Measurement topics too!

Area and Perimeter is an interesting topic for kids. I love it when they can relate to the real-world situations like putting a fence around the garden or laying grass in it.

This packet is already available in my store but I'm a little behind on updating it on my blog. I have been a busy bee of late ðŸ˜Š.

The topic begins with introducing Area and Perimeter. You may start with either of the two, but I prefer introducing Perimeter first and then Area. Later, I mix it up for them to practice.

### Perimeter:

Perimeter is the distance Around outside of a figure.

Area:
Area is the number of square units needed to Cover the region inside the figure.

Check out what’s included in my beginner’s worksheets and activities pack to learn and practice the concept of Area and Perimeter.

1. Measuring Perimeter
2. Measuring Area
3. Area Estimation
4. Area using Distributive Property
5. Perimeter Word Problems
6. Area Word Problems
7. Area and Perimeter Review
8. School Carnival activity for real-world application
9. Town Planning activity for a project

You can grab this area and perimeter resource from my store HERE.

### STAAR Math Grade 3 Practice Test

STAAR is almost here. Relieve the feeling of stress by having your students do a round of practice with this full-length 3rd Grade Math STAAR Practice Test. This mock test is aligned to the current TEKS and includes a total of 46 questions.

Student answer document/Bubble sheet and the Answer Key is also included. You can grab this practice test from HERE.

As the STAAR testing is a new experience for the 3rd graders, it is always helpful to administer a dry run for them to know what to expect in the real exam setting.

Best of luck to the little ROCK STAARS!

### Rounding of numbers to the nearest 10 and 100

Hi Everyone,

Today, I am going to share some of my work on the topic Rounding to the nearest 10 and 100. Typically rounding is introduced in Grade 3. The supporting common core standard is:

Math 3.NBT.A.1: Use place value understanding to round whole numbers to the nearest 10 or 100.

Rounding of a number means replacing it by another number that is approximately of equal value but making it simpler. This is an important skill for students to build on their number sense. For some students, performing rounding of numbers can be quite confusing. My motive was to make something simple, interactive and yet effective to help the little learners understand the concept of rounding.

I am a big fan of Anchor Charts which are created during the instruction of topic. These goes a long way in reinforcing the unit and students can reference it back too!

### Fact Fluency

Fact fluency refers to the ability to recall the four basic operations of math with ease and accuracy. A good grasp of these facts helps students to move up to more complex mathematical concepts like multi-digit addition, multi-digit subtraction, long division, and fractions.

Studies have shown that students who have good command over basic facts find mathematics more interesting than others. The basic math facts are also included in the common core curriculum for grades 1, 2, and 3.

Grade 1: Demonstrating fluency for addition and subtraction within 10.
Grade 2: Fluently add and subtract within 20 using mental strategies.
Grade 3: Fluently multiply and divide within 100.

Many teachers include basic math facts as a part of the daily morning work at school and also send those to practice at home. By the end of the school year, students develop their facts with automaticity.

As students have recently learned the basic operations, they need a ton of practice to master the fluency of these operations. I always like to have a lot of fact fluency worksheets and plan to use these over extended duration.

Here are some of my fact fluency packets.
1. Addition and Subtraction Fact Fluency - within 10
2. Addition and Subtraction Fact Fluency - within 20
3. Multiplication Fluency - Facts up to 12

Multiplication Fluency - Facts up to 12

A total of 35 Multiplication Facts Fluency worksheets for practicing the timed multiplication facts. Each worksheet includes a total of 60 questions in groups of 10.

### Equivalent Fractions

While teaching equivalent fractions, the very first question that I always ask my students is: What does equivalent means? The answer comes “Equal”.

Yes, Equivalent means Equal in Value or Amount.

Two or more fractions are said to be Equivalent if they represent the same part of a whole.

Example:

These two models are of the same size and both shows the equal shaded parts of a whole. So,
$$\frac{1}{3}\textrm{ is equivalent to }\frac{2}{6}$$
Another way of showing equivalent fractions is using the number line. Lets look at the same example:

These two red dots are on the same point on the number line and represents the equivalent fraction.
$$\frac{1}{3}\textrm{ is equivalent to }\frac{2}{6}$$

## Finding Equivalent fractions

Every fraction has many equivalent fractions. You can find these by using multiplication or division.

Multiplication: Multiply the numerator and denominator by the same number. For example:
$$\frac{1}{3} \times \frac{2}{2}=\frac{2}{6}$$
$$\frac{1}{3}\textrm{ is equivalent to }\frac{2}{6}$$

Division: Divide the numerator and denominator by the same number. For example:
$$\frac{5}{10} \div \frac{5}{5}=\frac{1}{2}$$
$$\frac{5}{10}\textrm{ is equivalent to }\frac{1}{2}$$
Here is my Equivalent Fractions worksheet and activity pack to introduce, reinforce and practice the concept. This packet is designed primarily for third graders, but can also be used as a review for fourth graders.

This includes the following worksheets and activities on equivalent fractions:
1. Use the fraction area models to complete the number sentence.
2. Use the number line to find the equivalent fractions
3. Find the equivalent fractions without the use of models
4. Equivalent Fractions Ice cream scoop activity
5. Cut and paste activity
6. Make Equivalent Fractions Paper Chain
7. Equivalent Fractions Mystery Pictures

A total of 15 worksheets and activities plus the answer key.

Happy Teaching!
