Focus: Estimating Sums

Learning Target: I can use close numbers to estimate sums and differences.

Task: COPY these perfect models in your notebook to use as a reference:

1.34 + 2.53 = 0.5 + 0.37 = 3.17 + 1.86 =

Twenty-one hundredths + Three and seventy-nine hundredths =

1. COMPLETE some of the slideshow. Change the values to the nearer half or whole. Then solve for the estimated sum.

Slides 1 - 4.

2. Use the place value discs to solve for the sum.

Slides 5 - 13 ONLY.

Task: CLICK on the Google Classroom button for your class below.  

1. COMPLETE the Adding Decimals #1 Slideshow. 

   • READ directions on Slide 2.

   • WATCH video on Slide 3. Might need to watch more than one time.

   • CHECK with Mr. Blaser or Mr. Weiss after Slide 4.

   • FINISH the remaining slides. DON'T DO STANDARD ALGORITHM...ONLY MODEL!

2. In your math notebook, show your work with a rough sketch for modeling three of the five problems. Remember to use 2 different colors. DO THIS AFTER SLIDESHOW COMPLETED.

Learning Target: I can calculate the sum of decimal values using a model with Base Ten pieces.

Task: Play GREATEST SUM

1. 1. Use the blank template slides from the handout to model an addition problem for 4 rounds.

   2. Each round the computer will generate 4 cards: RANDOM.ORG

      1. First two cards represent the first addend. Next two cards represent the second addend.

      2. RED cards equal tenths. Black cards equal hundredths. Most Face Cards equal 1 whole (Jack equals 0 tenths or 0 hundredths depending on color.).

   3. Write the problem on the slide. Model. Solve.

   4. Check opponent's work...zero points for incorrect sums.

   5. Total your score after 4 rounds to determine winner. May use a calculator.

Task:  

1. COMPLETE any 4 of the problems using a model:

   • Use two colors.

   • Number & write ALL of the equations above the flats used for that problem.

   • Draw a fence around each problem to help separate one from another.

   • Get checked when finished.
