In this unit, students will learn:

• the value of tenths and hundredths 
• a number can be represented as both a fraction and a decimal (.1 =1/10 or .32 = 32/100)
• decimal notation (write numbers in standard form 0.62)
• comparisons are valid only when two decimals refer to the same whole
• Compare decimals using visual models and symbols.
• Add two fractions with unlike denominators of 10 and 100

Essential Questions:

• How do adding and subtracting fractions help me in everyday life?
• How can I join fractions with like denominators?
• How can I separate fractions with like denominators?
• How can I convert a fraction greater than 1 into a mixed number?
• How can I add and subtract mixed numbers with like denominators?
• How can I represent unit fractions in a line plot?
• How can I add and subtract fractions found in a line plot?

In this unit, students will be able to:

• Join (compose) fractions of the same whole
• Separate (decompose) fractions of the same whole in various ways (e.g.
• Justify decompositions (e.g., by using a visual fraction model).
• Convert a fraction greater than one (formerly referred to as an improper fraction) into a sum of a whole number and a number less than one
• Add and subtract mixed numbers with like denominators using various strategies (e.g., replacing each number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction).
• Solve word problems involving addition and subtraction of fractions with like denominators (e.g., by using visual
  fraction models and equations to represent the problem.

What students will be able to do by the end of the unit:

• Recognize and read numbers up to 1,000,000 in word form, standard form, and expanded form
• Write and represent numbers up to 1,000,000 in word form, standard form, and expanded form
• Use place value strategies to compare and order numbers
• Round and estimate numbers
• Fluently add and subtract numbers (with regrouping) using the standard algorithm

 

Key Terms

Expanded Form - a way to write numbers by showing the value of each digit

Word Form - a way to write numbers by using words

Standard Form -a way to write numbers by using the digits 0-9 with each digit having a place value

Rounding - to replace a number with another number that tells about how many or how much

Estimate - a number close to an exact amount

Period - each group of three digits separated by commas in a multi-digit number

Compare - to describe whether numbers are equal to, less then, or greater than each other

Place Value - the value of a digit in a number, based on the location of the digit
