Clarifications


Clarification 1: When comparing numbers, instruction includes using a number line and using place values of the hundreds, tens and ones digits.

Purpose and Instructional Strategies

The purpose of this benchmark is to extend the place value work of plot, order and compare from grade 1 by increasing the number set to 1,000. 
  • Instruction includes the use of numbers presented in multiple ways and different forms. 
  • Instruction includes the understanding that the value of a digit is impacted by its position in a number. 
  • Instruction includes the use of place value charts, place value cards, place value disks, place value chips and base ten blocks (MTR.2.1). 
  • Instruction includes the use of number lines using benchmark numbers to support comparing. 
  • Instruction includes the understanding that numbers can be reordered in both ascending and descending order.

 

Common Misconceptions or Errors

  • Students may incorrectly plot a three-digit numbers in a number line.
  • Students may not understand that a representation of a smaller portion of a number line (200 − 220) may have the same physical size as a representation of a larger number line (0 − 1,000). 
  • Students may have difficulty comparing two numbers that have the same digits in a different order (i.e., 852 and 582).

 

Strategies to Support Tiered Instruction

  • Instruction includes the use of a hundreds chart and base ten blocks. Teacher shares two numbers that have the same digits, but the numbers are in different places. 
    • For example, using numbers like 852 and 582, the students build the two numbers on place value charts. Teacher has students write the number under each of the base ten blocks representation. With the visual representation of the numbers available, ask which number is greater and which number has fewer of each of the base ten blocks. If students identify the incorrect number, teacher points out that there is a greater number of hundreds/flats in 852 than in 582.

 

Instructional Tasks

Instructional Task 1 (MTR.2.1

Provide students with five numerals (i.e., 1, 8, 5, 4 and 0). 
  • Part A. Create four different three-digit numbers that have a 4 in the hundreds place. 
  • Part B. Arrange the numbers created in order from greatest to least. Explain why which number is the greatest. 
  • Part C. Using two of the numbers created from Part A, write a statement using > or < to compare.

 

Instructional Items

Instructional Item 1 

Use the number line below to plot the numbers 234, 247, 205. 

line

Instruction Item 2 

Use <, > or = to make the comparison statement 567 __ 576 true.

Formative Assessments

Name Description
Using Digits

Students randomly pull five cards from a set of digit cards and use them to make the greatest and least three-digit numbers possible. They are also asked to use the greater than or less than symbols to compare the two numbers.

Who Has More?

Students are asked to compare two numbers used in a word problem and to write an inequality statement showing the relationship between the numbers.

Inequalities Using Symbols

Students are asked to compare numbers and then use the greater than, less than, or equal to symbols to complete inequality statements.

Missing Digits

Students are asked to compare numbers with missing digits and explain their reasoning.

Lesson Plans

Name Description
Pop, Pop, Pop!

Students will research the effects of sugary drinks on their health.  They will interpret data on a variety of beverages presented in the form of bar graphs and decide which beverages should be included in school vending machines to ensure students have healthy drink options.

Less Than, Equal to, or Greater Than?

In this lesson, students move from comparing three-digit numbers built with base ten blocks to comparing three-digit numbers based on their place value. Students will use the greater than, less than, or equal sign to compare their values.

Carnival

Written at a second grade level, in this MEA the students will use problem solving skills, two-digit addition, and knowledge of greater than and less than to rank order carnival games based on provided criteria.

Restaurant Rankings: Which meal would you want to add to your cafeteria menu?

The students have been selected by the cafeteria manager to help rank healthy meal options that have been proposed to be added to the school cafeteria. The students will use information about the food and drink included in the meal, total calories, sodium content, calories from saturated fat, and calories from sugar to come up with a procedure for ranking the meal options. Then students will have to use or adapt their original procedures to include two more meal options in the rankings.

Chocolate Delight

Although, chocolate sales in America have continued to grow, due to the increased awareness of childhood obesity, there is major concern about the nutritional value of chocolate candy bars. Chocolate Delight, a chocolate bar company, wants to improve its sales to elementary students by creating a healthy chocolate bar. They have tested 5 new recipes and need to determine which candy bar is best for children. The students will rank the recipes from best to worst based on the following criteria: healthiness, taste, and nut allergies and make a recommendation of the healthiest recipe to Chocolate Delight.

Symbol Spin

This lesson puts a spin on comparing three-digit numbers! The students will work cooperatively to compare two three-digit numbers based on the hundreds, tens, and ones place values. The students are encouraged to verbally explain their logic during the game. This is a lesson that will engage your students and can last all week long!

Less Could Be More!

Digits 2-5-7

Students who are struggling to build an understanding of the relationship between digit placement and the value of the number may still need concrete manipulatives such as grid paper and Base Ten Blocks. As a classroom extension, after students have worked independently or in small groups to solve the problem, the teacher can ask students to share their numbers, until all six possibilities are listed. Then, independently or as a whole group, students can order the six numbers from smallest to largest (or largest to smallest).

Ordering 3-digit numbers

The purpose of this task is for students to gain a better understanding of 3-digit numbers and their place value.

Comparisons 1

This task requires students to compare numbers that are identified by word names and not just digits. The order of the numbers described in words are intentionally placed in a different order than their base-ten counterparts so that students need to think carefully about the value of the numbers. Some students might need to write the equivalent numeral as an intermediate step to solving the problem.
