Decimals Greater Than 1 - Co-Taught Lesson Plan printable pdf download

Co-taught Lesson Plan

Name of Lesson Plan: Decimals > 1 Grade Level: 3

Topic: Decimals Greater than 1 Time required: 50 min. Space: Classroom

Preparer: Christina Millson (co-taught with Massaro and Miller) Audience: Whole Group

Number of Students: 22

Resources: document camera, projector, math journal, base ten blocks (3 packages), glue sticks,

lined paper, pencils, three teachers

VA SOL:

3.7 The student will read and write decimals expressed as tenths and hundredths, using

concrete materials and models.

Behavioral Objectives:

Given base ten block manipulatives and concrete models, students will write numeral

representation of model in fraction and decimal form.

Given base ten block pictorial models and numeral forms of decimals, students will match the

decimals and pictorial models.

Lesson Description:

Introduction: (Christina Millson) Explain to students they will be completing a quick chart

(see attached) to make sure they understand tenths and hundredths. Pass out chart and have

students complete for a grade. Once complete ask students to exchange papers and grade chart

as a class.

Then introduce decimals greater than one, explaining that up to this point the students have only

been working with decimals less than one.

Content Focus: (Christina Millson) Model a decimal greater than one with base ten

manipulatives (such that the flats equal one whole, sticks equal one tenth, and cubes equal one

hundredth). Model decimal 1.0 by explaining to students that ten tenth sticks make up one

whole, or in fractional terms 10/10 equals one whole.

Model decimal 1.1 using one flat and one tenth stick. Explain that the flat represents one whole

and the tenth represents 1/10 or one tenth. The fraction is said one and one tenth, just as the

decimal is also said one and one tenth.

Model 1.2 using one flat and two tenths. Ask students to write down decimal in their math

journals. The decimals is 1.2.

Then model 1.3 and have the students write the decimal. Finally model 1.4 and have students

write the decimal.

(Millson, Massaro, Miller) After they have grasped the concept it is time to split into three

groups based on ability. In each group, continue modeling fractions greater than one with the

manipulatives. Ask students to write down fraction and decimal for each model. Once students

understand tenths, move onto decimals greater than one with hundredths. Model one flat, one

tenth, and one hundredth. Explain that there are eleven hundredths because the little cubes

represent hundredths. Have students write down fraction (1 and 11/100) and decimal (1.11).
