1 EXPLORING FRACTIONS WITH TEAM FRACTION ACTION Adding Fractions with Like Denominators

2 Through the following activities you will learn to add fractions with like denominators, simplifying your answers when necessary. Lesson Objective Next Back

3 A working computer and mouse Internet access Paper and pencil A positive attitude and willingness to explore fractions What you need to get started Next Back

4 Main Menu Click on a box to the right to access a specific part of the lesson. Part 1: Finding Fractions within Pattern Blocks Part 1: Finding Fractions within Pattern Blocks Part 2: Adding Fractions with Like Denominators Part 2: Adding Fractions with Like Denominators Part 3: Guided Practice with Adding Fractions Part 3: Guided Practice with Adding Fractions Part 4: General Assessment Part 4: General Assessment Back Next

5 Finding Fractions within Pattern Blocks Part 1: Next Back

6 Introduction to Activity In this first activity you are going to be filling large pattern blocks with smaller shapes, as shown on the hexagon pictured to the left. How many equilateral triangles are in this hexagon? Next Back

7 Finding Fractions within Pattern Blocks As you can see, 6 equilateral triangles fit inside this hexagon. That means that each triangle is one sixth of the whole hexagon. Next Back

8 Now its your turn to explore! Would you like to play with virtual pattern blocks? Take some time to explore the pattern block program before we begin the activity. If you have any questions, raise your hand. Have fun and come back in 3 minutes! Next Click here to access virtual pattern blocks. Back

9 Use your pattern blocks to help you answer the following question. How many are in a ? Next Give this problem a try! Back Return to the virtual pattern blocks to figure out the answer!

10 We can see that 2 triangles fit inside 1 rhombus. We know that each triangle is ½ of the whole rhombus. Next Back

11 Use your pattern blocks to help you answer the following question. How many are in a ? Next Return to the virtual pattern blocks to figure out the answer! Lets try this one! Back

12 Next We can see that 3 triangles fit inside 1 trapezoid. We could represent this mathematically with the following addition sentence. Can you figure out which parts of the sentence are accounting for the triangles? What about the trapezoid? Back

13 Use your pattern blocks to help you answer the following question. How many are in a ? Next See if you can figure this one out! Return to the virtual pattern blocks to figure out the answer! Back

14 We can see that 2 trapezoids fit inside 1 hexagon. We know that each trapezoid is half of the whole hexagon. Try to make the addition sentence that corresponds to this picture. Click here to see the answer! Back

15 Next This picture represents the following addition sentence: We can see that there are 2 trapezoids that each cover half of the hexagon each. Each ½ represents one of the trapezoids, the 1 represents the whole hexagon that is covered. Back

16 Use your pattern blocks to help you answer the following question. If =1, then = ___? Next This ones a little different… Return to the virtual pattern blocks to figure out the answer! Back

17 We can see that 3 triangles fit into 1 trapezoid. If 3 triangles fit into 1 whole (the trapezoid), then each triangle is 1/3 of the trapezoid. Are you stuck? Click here to look back at a hexagon example that is similar to this one.here Next Back

18 Finding Fractions within Pattern Blocks As you can see, 6 equilateral triangles fit inside this hexagon. That means that each triangle is one sixth of the whole hexagon. Next Back

19 Use your pattern blocks to help you answer the following question. If =1, then = ___? Next Try one more! Return to the virtual pattern blocks to figure out the answer! Back

20 We can see that 2 trapezoids fit into 1 hexagon. If 2 trapezoids fit into 1 whole (the hexagon), then each trapezoid is ½ of the hexagon. The numerator 1 tells us we are talking about one part out of the 2 total parts (the denominator) in the whole. Next Back

21 Making and solving fraction addition sentences can be easy when you think about the fractions being small parts of a larger shape. Now, youre going to learn another way to solve fraction addition problems. Next Great work so far! Back

22 Lesson on Adding Fractions with Like Denominators Part 2: Next Back

23 Adding Fractions Quickly and Easily Now you are going to watch a video to show you exactly how to add fractions. You can always pause the video and raise your hand if you have a question. If you are ready to begin, click in the box below! Next Click here to begin the lesson on adding fractions. Back

24 Extra Practice with Adding Fractions Part 3: Next Back

25 Try these! Click here for the answers to these practice problems. Back Next

26 The 2+1 in the numerator gives us 3, then the denominator stays the same since our whole stays the same. As you can see from the diagram, three-sixths can simplify to be ½. Back How did you solve the 1 st problem?

27 Next The 3+2 in the numerator gives us 5, then the denominator stays the same since our whole stays the same. As you can see from the diagram, five-fifths is equivalent to 1. How did you solve the 2 nd problem? Back

28 Next The 7+2 in the numerator gives us 9, then the denominator stays the same since our whole stays the same. Nine-tenths cannot be simplified. How did you solve the 3 rd problem? Back

29 Adding Fractions Assessment Part 4: Next Back

30 Its time to show what you know! You will be given a test to complete showing what you have learned about adding fractions with common denominators. Do your very best; if you have a question raise your hand! Back
