The Data Analysis Unit involves organizing and displaying data in a variety of ways in order to answer questions such as:

• What is the difference between discrete and continuous data? In other words, why is it OK to connect the dots on a time and temperature graph but not on a favorite color graph?

• What is the difference between categorical and numerical data? In other words, does the order of the data matter on a favorite pizza graph? Does the order of the data matter on an age and height graph? Why or why not?

The Coordinate Plane Unit provides the introduction to identifying locations on a coordinate plane. Questions to answer may include:

• How is a coordinate grid used to find a specific location in 2-dimensional space?

• What is the “first quadrant of the coordinate plane”? If there is a “first quadrant”, are there also second, third, and fourth quadrants? If so, how are they defined? How are they used to locate points?

The Measurement Unit involves applying the process of measuring to quantify attributes that can be measured (length, area, volume, capacity, weight/mass and time). Questions to uncover the process of measuring may include:

The Geometry Unit involves analyzing the defining properties of 2-dimensional shapes in order to answer questions such as:

• What are the relationships between the sides of this shape?

• How are these relationships used to define the shape?

The Algebraic Reasoning Unit involves understanding the properties of numbers, understanding and generating number patterns, and using the properties and patterns to develop meaning for expressions and equations. Questions to answer may include:

The Dividing with Fractions Unit develops meaning for situations involving dividing a whole number by a unit fraction and dividing a unit fraction by a whole number. Questions asked when dividing whole numbers provide meaning for situations involving division with fractions:

• When a quantity is shared equally, what is the size of each share? When `1/4` is shared equally among 5, what is the size of each share: `1/4` ÷ 5 =  ?

• How many groups of a given size are in this whole number? How many `1/4`s are in 5:5 ÷ `1/4` =  ?

The Adding and Subtracting Fractions Unit involves using a variety of methods to join or separate parts referring to the same whole. Questions to answer may include:

• Why must we refer to the same “whole” when adding or subtracting fractional parts?

• How can a number line be used to represent adding or subtracting fractions?

• How can benchmark fractions help to determine whether a sum or difference is reasonable?

The Products and Quotients with Decimals Unit involves using patterns and place value to develop strategies to multiply and divide decimals. Questions to answer may include:

The Operations with Whole Numbers Unit involves using patterns and place value to apply strategies to perform all four operations with whole numbers. Questions to answer may include:

The Decimal Place Value Unit involves understanding and representing the relative position, magnitude and relationships within the numeration system in order to answer questions such as:
