General Information
Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
Test Item Specifications
Decimals may reference the same whole entity. Decimals are limited to tenths and hundredths. Decimals may be greater than 1. Items may not require a comparison of visual models in isolation.
No

Sample Test Items (4)
| Test Item # | Question | Difficulty | Type |
| Sample Item 1 | Mr. Shelby bought a new plant. The plant grew 2.6 centimeters in the first week
and 3.42 centimeters the second week. Select all the true comparisons of the plant growth for the two weeks.

Formative Assessments
| Name | Description |
| Using Models to Compare Decimals | Students are asked to compare decimals by drawing a visual model and record the comparison using the less than, greater than, or equal to symbol. |
| Comparing Decimals in Context | Students are asked to compare two pairs of decimals in the context of word problems and to record a comparison using an inequality symbol. |
| Comparing Four Tenths | Students are asked to consider two grids with different sized wholes and determine if both models show four-tenths. |
| Compare Decimals | Students are asked to compare four pairs of decimals using the less than, greater than, or equal to symbols. |
Lesson Plans
| Name | Description |
| Cell Phone Inquiry | Students will determine what cell phone would be the best phone for their teacher to purchase for science class. Factors to consider are price, touch screen, camera, voice command, weight and display size. Students will need to compare decimals to determine how to order and rank the phone brands. Model Eliciting Activities, MEAs, are open-ended, interdisciplinary problem-solving activities that are meant to reveal students’ thinking about the concepts embedded in realistic situations. Click here to learn more about MEAs and how they can transform your classroom. |
| Comparing and Ordering Decimals | In this cooperative learning activity, students will have five sets of decimal cards to sort and put in order - least to greatest. The lesson starts with a short whole group activity and then breaks off in to structured groups. The teacher is free to interact with each of the groups and monitor progress, participation, and understanding. |

Problem-Solving Task
| Name | Description |
| Using Place Value | Each part of this task highlights a slightly different aspect of place value as it relates to decimal notation. More than simply being comfortable with decimal notation, the point is for students to be able to move fluidly between and among the different ways that a single value can be represented and to understand the relative size of the numbers in each place. |
