Eureka Math Lesson 3

432 Words2 Pages

During the sixty-minute lesson, the students will use numbered disks (manipulative) and a place value chart to exchange smaller units for a larger unit. This lesson teaches students to represent a number with the smallest number of units possible. This lesson builds on the student’s prior knowledge of the base ten strategy, and helps them make connections between the individual units (ones, tens, and hundreds). Students can also use their prior knowledge of expanded form (127 = 100 + 20 + 7) to categorize the correct number of units into the place value chart. This lesson implements the use of the benchmark strategy, as a scaffold for students to find an even ten or an even hundred. The goal of this lesson is for students to apply their knowledge of place value (ten ones, makes a ten & ten tens, makes a hundred) to represent three digit numbers using the smallest number of units possible. …show more content…

This lesson emphasizes exchanging units, which is a skill that will be used and built on in later modules. This lesson aligns with second grade math state standards and the Eureka math curriculum.

SCCCR-MATH-2015.2.NSBT.1.a
100 can be thought of as a bundle (group) of 10 tens called a “hundred”;
SCCCR-MATH-2015.2.NSBT.1.b
the hundreds digit in a three-digit number represents the number of hundreds, the tens digit represents the number of tens, and the ones digit represents the number of ones;

2.MP.1. Make sense of problems and persevere in solving them.

2.MP.2. Reason both contextually and abstractly.

The student will be able to represent a three-digit number using place value

Standard 3.OA.1:  Interpret products of whole numbers, e.g., interpret 5 × 7 as the total number of objects in 5 groups of 7 objects each. For example, describe a context in which a total number of objects can be expressed as 5 × 7. Children start working with equal groups as a whole instead of counting it individual objects. Students start understanding that are able to group number is according to get a product. Students can solve duplication by understand the relationship between the two number.

In Math, Scott is working on developing a strategy to help him solve one-digit and two-digit multiplication problems. He has been exposed to the Bow-Tie method for two-digit, grouping and the array strategy for one-digit multiplication. He is doing very well at understanding and using the method to assist him in solving the multiplication problems. There have been improvements in his assessments by creating a strategy that works for him. After Scott has used the strategy over time, he will develop automaticity for solving the multiplication.

Guided Practice PERFORMANCE TASK(S): The students are expected to learn the Commutative and Associative properties of addition and subtraction during this unit. This unit would be the beginning of the students being able to use both properties up to the number fact of 20. The teacher would model the expectations and the way the work is to be completed through various examples on the interactive whiteboard. Students would be introduced to the properties, be provided of their definitions, and then be walked through a step by step process of how equations are done using the properties.

“One thing is certain: The human brain has serious problems with calculations. Nothing in its evolution prepared it for the task of memorizing dozens of multiplication facts or for carrying out the multistep operations required for two-digit subtraction.” (Sousa, 2015, p. 35). It is amazing the things that our brain can do and how our brain adapt to perform these kind of calculations. As teachers, we need to take into account that our brain is not ready for calculations, but it can recognize patterns.

I wanted to write this unit for 9th grade because I love how 9th graders are still young and getting use to high school; therefore, I believe they will be more willing to get up and try new things. This unit includes the exploration of The Real Number System, specifically rational numbers, irrational numbers, and exponents and how they relate to the Real Number System. By exploring the exponents first, we see how various exponents effect each number. For example, 3^-2 makes the number 1/9, but 3^2 is just 9.

First I thought, “How do I go about explaining the concept of hundreds and thousands to kids who are obviously still struggling with the fundamentals of reading, writing, and spelling; as well as mathematics?” Then I started to contemplate on how much the school system has changed, and how much it has stayed the same since I was their age, and that I would have to change my tactics in order to adjust with the times, as well as different students ranging from a diverse set of schools from various ages and grade levels; thus being one of the biggest challenges of all, as a future educator. When I was their age, each and every student had their very own EAI Education Grade–Level Math Kits; which helped with identifying the different shapes, colors, and patterns. It allowed us to tell time and differentiate between hot and cold temperatures.
