### Lesson Objective

SWBAT compare and order decimals. SWBAT compare fractions and decimals.

### Lesson Plan

 Standard 6NSO.N2 – Compare and order positive and negative fractions, decimals and mixed numbers and place them on a number line 6NSO.N5 – Identify and determine common equivalent fractions, mixed numbers, decimals and percents. Aim/Objective: Key Points ·         Compare and order decimals ·         Compare fractions and decimals ·         Compare decimals by comparing digits in the same place value ·         To compare fractions and decimals we should first put them both in the same format. Assessment: Compare  0.078 ____ 0.8   Order from least to greatest 0.5, 0.05, 0.55, 0.505   Compare  ¼ ____0.14   Compare 3/5 ____ 0.6 Lesson Warm Up: ·         3 problems converting fractions to decimals ·         Review the key points of converting fractions to decimals – top number in the box. Divide.   Opening: ·         We are going to work today to compare decimal numbers ·         After we can compare decimals, we will work on comparing decimal numbers to fractions. Intro/Direct Instruction: ·         Model for students writing decimal equivalents.  Highlight that 0.4 and 0.40 are the same number using a fraction model. ·         Have students write decimal equivalents to a certain place ·         Model for students that we can compare decimals using a decimal place value chart.  The reason this helps is because it forces us to line up our digits according to their place value and therefore we can compare them easily. ·         Have students practice comparing decimals using a place value chart ·         Model for students ordering decimals – highlight that we should always look to see if we are ordering them from least to greatest or greatest to least. ·         Have students order decimals ·         Model for students comparing fractions to decimals ·         Tell students that the first thing we should do is put them in the same format – discuss the saying comparing apples to oranges – and that it’s harder to compare things that aren’t alike ·         Model for students comparing by changing both into decimals ·         Model for students comparing by changing both into fractions ·         Students practice comparing fractions to decimals ·         Students practice independently comparing, ordering decimals ·         Students independently practice compare fractions to decimals.   Closing ·         Review key points ·         Exit Ticket
