## From Patterns of Input and Output to Algebraic Equations

Students explore the relationship between input and output values and learn to use algebraic expressions and equations.

4-8

Lesson Plan

## Addition of Decimal Numbers and a Common Error

Students practice carefully lining up decimal places while calculating sums of decimals that total more than one.

4-7

Lesson Plan

## Balancing Number Sentences to Introduce Missing Values

Students learn about balancing equations and keeping an equation balanced by adding/subtracting the same amount to both sides of the equation. Students solve missing value problems and justify their solutions.

3-6

Lesson Plan

## Basketball as a Context for Percentages

Students learn to associate simple fractions (25%, 50%, 75% as well as 20% and multiples) of wholes with equivalent percentages in the context of basketball scores and stadium capacity.

5-8

Lesson Plan

## Building Venn Diagrams

Students utilize Venn diagrams in an introduction to prime numbers, prime factorization and determining least common multiple (LCM) and greatest common factor (GCF).

4-8

Lesson Plan

## Calculating Elapsed Time

Students practice the concept of time passage by counting, subtracting and regrouping in base 60.

2-5

Lesson Plan

## Catching a Kidnapper

The students learn about body matches and measuring one part of the body using another body part. They learn about non-standard measures and relative measurement.

2-5

Lesson Plan

## Counting and Place Value

Students explore counting through the concept of place value in our base-10 numeration system. They practice grouping in groups of ten and groups of ten tens.

2-5

Lesson Plan

## Counting into the Ten-thousands

Students are introduced to place value into the 10,000s through the use of an abacus. They practice writing and recognizing large numbers.

3-6

Lesson Plan

## Creating Equal Shares

Students practice fractions by sharing certain numbers of objects among different numbers of people. They begin with unit fractions and move to sharing multiple objects among multiple people, in which a < b, and to produce fractions less than one.

3-6

Lesson Plan

## Data Clusters and Distributions

Students learn about statistics through the use of surveys. They also learn to examine the shape of data including data clusters, the range, and typical values.

3-6

Lesson Plan

## Defining, Describing and Calculating Rate

Students explore their prior knowledge of rate and extend it to create tables of values coordinating time and distance. They learn how to examine distance-time graphs and how to calculate unit rates.

5-8

Lesson Plan

## Describing Range and Measures of Central Tendency in Shoe Sizes

Students are introduced to various measures of central tendency (range, mode, median, and mean) and they explore the advantages and disadvantages of each measure.

5-8

Lesson Plan

## Determining Rates from Graphs

Students learn about and practice calculating rates (positive, negative and zero) using data from graphs.

4-8

Lesson Plan

## Diagnosing Allergies through Data Collection

Students practice data collection by gathering data within the classroom on common causes of allergies. They examine and interpret data charts on national trends in allergies.

4-7

Lesson Plan

## Elapsed Time and Scheduling

Students practice time management by making their own schedules. They learn to calculate elapsed time in both digital and analog formats.

3-6

Lesson Plan

## Equivalent Fractions as a Means to Compare

Students learn to create equivalent fractions between fifths and tenths (and then some other denominations) as a means to compare fractions of like denominators.

3-6

Lesson Plan

## Estimating Distance and Time

Students learn to estimate the time it takes to travel different distances based on an estimation of the time it takes to travel a part of the whole route. This reinforces basic fractional/ratio thinking, as well as early multiplication as repeated addition.

3-5

Lesson Plan

## Estimating Profit from a Job

Students learn about estimation and rounding and practice rounding with decimal points.

5-8

Lesson Plan

## Estimation

Students practice their estimation skills by estimating time and numbers of objects in situations in which counting is not feasible or necessary.
