Essential Questions for this unit are:

- How are decimals related to the base ten number system? Decimals and Fractions
- How do I apply the use of fractions and decimals in everyday life?
- What strategies can I use to find the unknown value in fractional computation? Weight
- What relationships can be found within the standard system or metric system of measurement?
- . What happens to the measurement of an object when I change the unit of measurement? Data Analysis
- How can graphing patterns be used to predict what will happen next?
- What are the advantages of working with a line plot?

When we complete this unit, students should have an enduring understanding of the following topics:

- Parts of a whole or set may be represented in a variety of ways - fractions, decimal fractions, improper fractions, and mixed numbers.
- When fractions, decimal fractions, improper fractions or mixed numbers are added or subtracted the same rules of computation apply as for whole numbers.
- Fractional parts are equal shares of a whole. The size of a fractional part depends on the size of the whole.
- Equivalent fractions are different ways of describing the same amount using different fractional parts.
- Decimals are another way of writing fractions. The decimal point separates the whole from the fractional part.
- There are two systems of weight, customary and metric. Measurement is a comparison of the object being measured with a "unit". Comparison of units can only be made within the same system e.g. grams can be compared to kilograms but not to ounces.
- Trends and generalizations can be made by analyzing data within a graphical representation.
