Week 11

(Module 1 Topic 3 Lesson 2: Adding + Subtracting Decimals)

Learning objective = Students use place value to estimate sums and differences of decimals and then develop standard algorithms. They solve real-world problems by first determining whether they need to add or subtract, using estimation to predict the magnitude of the answer, and then applying the standard algorithm. Students play a calculator game to target place value in subtraction.

Parents can support learning at home by helping students connect this week’s lesson to real-life examples and practice explaining their thinking. Encourage your child to explain each step aloud rather than simply memorize a rule = SAMPLE TEST QUESTIONS + MORE QUESTIONS

***If your child needs more challenge, they can move at a faster pace by using this site to study the concepts of future lessons. Mr. Pierre will strive to prepare lessons two weeks ahead of the current week. Also, Khan Academy is a great enrichment resource***

How Far to Wells Road? | Cyberchase | Grades 3-5, 6-8 Performing Multi-Digit Arithmetic With Place Value Teaching and Lesson ResourcesIn this video segment from Cyberchase, Bianca is driving to visit her friend. Her driving instructions say that she has to drive 3.2 miles and then make a turn. She checks her car odometer and calculates the distance she must drive by adding the 3.2 miles to the odometer reading. Unfortunately, she makes a calculation error and ends up driving too far.
