Objective: 

• Students will multiply multiple digit numbers, including numbers with decimals.

• Students will compare decimals and be able to round to the nearest whole number.

• Students will use rounding to whole number as a strategy for finding reasonable answers to decimal multiplication problems. 

Standard written out: 

5.NR.2.1 Fluently multiply multi-digit (up to 3- digit by 2-digit) whole numbers to solve authentic problems. 

5.NR.4 Read, write, and compare decimal numbers to the thousandths place, and round and perform operations with decimal numbers to the hundredths place to solve relevant, mathematical problems. 

Objective: 

1. Students will model tenths using fraction circles (or other manipulatives) to represent fractions with a denominator 10. 

2. Students will relate tenths to decimals, writing tenths in decimal form (e.g. 3/10 = 0.3).

3. Students will compare and order tenths using visual models (fraction circles) and reasoning (which is larger/smaller).

MGSE4.NF.6
Use decimal notation for fractions with denominators 10 or 100.

• For example: write 3/10 as 0.3 and 62/100 as 0.62; describe a length as 0.62 meters; locate 0.62 on a number line diagram.

MGSE4.NF.5
Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with denominators 10 and 100.

• For example, 3/10 = 30/100, so 3/10 + 4/100 = 34/100.

GEORGIA STATE STANDARD:  

This lesson doesn't have a plan. It was impromtu, but it shows how to support student reasoning through discussion.
