Fraction and Decimal Garden

Cindy Jacobs

Description

Students write fractions and decimals using unifix cube models and grid paper. They draw a garden using grid paper and label each section with the correct fraction and decimal to the tenths.

Objectives

The student identifies equivalent forms of numbers.

Materials

-Dime
-Chalk
-Grid Paper
-Unifix Cubes
-Crayons

Preparations

1. Gather materials needed for this lesson.

Procedures

1. Show the class a dime. Ask how many pennies it takes to equal one dime? (10) What fraction of a dime is a penny? (1/10) Show students how to write 1/10 as a decimal.(0.1)

2. Draw a large rectangle on the chalk board. Divide it into ten equal sections. Shade inside two sections, and draw stripes inside one section. Ask students how many sections in all? (10) Ask how many sections have stripes? (1/10) Show them how to write this as a fraction (1/10) and decimal (0.1) above the striped section. Next, ask students how many sections are shaded? (2/10). Write the fraction above this section. Ask them how to write it as a decimal (0.2). Write the decimal above this section beside the fraction. Ask how many sections do not contain stripes or shading? (7/10) Write the answer as a fraction and decimal.

3. Pass out grid paper.

4. Instruct students to get out a red, green, and yellow crayon.

5. Connect ten unifix cubes (6 green and 4 red cubes). Have students draw and color the unifix model on their grid paper. Ask how many cubes are green? (6) Have them write the fraction and decimal to represent the number of cubes that are green. (6/10 and 0.6). Write the answers on the chalkboard. Check papers for accuracy. Next, ask students how many cubes are red? (4). Have them write the fraction and decimal to represent the number of red cubes (4/10 and 0.4). Write the answers on the chalkboard. Check papers for accuracy.

6. Repeat step #5 only use 3 yellow cubes and 7 green cubes.

7. Tell students to draw a rectangle on their grid paper that is 10 x 10. Demonstrate this on the chalkboard.

8. Tell them they will create a garden using the following color key:

Yellow = Corn
Red = Tomatoes
Green = Watermelon
Write the color key on the chalkboard.

9. Next, tell students that 2/10 of their garden is to be corn, 5/10 should be tomatoes, and 3/10 should be watermelons. You'll need to write the fraction beside each color on the color key.

10. Students should color their garden accordingly, label with the given fraction, and write the correct decimal beside each fraction.

11. Collect papers for assessment purposes.

Assessments

1. Mastery and non mastery will be based on how well students draw and label their gardens. Each garden should be colored and labeled correctly (see steps 7 - 10 of the procedures). Gardens should be completed with 80 % accuracy or better. Students who are having difficulty should receive feedback and extra time to make the corrections.

Extensions

Students could plan, prepare, and plant an actual garden using fractions and decimals to determine how many sections of each plant will be planted. Also, students could be served rectangular shaped pizza, cake, cookie, graham crackers,etc. to cut or break into fractional pieces to represent fractions and decimal to the tenths.
