Use place value understanding and properties of operations to add and subtract
MGSE2.NBT.6 Add up to four two-digit numbers using strategies based on place value and properties of operations.
MGSE2.NBT.7 Add and subtract within 1000, using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method.
MGSE2.NBT.8 Mentally add 10 or 100 to a given number 100–900, and mentally subtract 10 or 100 from a given number 100–900.
MGSE2.NBT.9 Explain why addition and subtraction strategies work, using place value and the properties of operations.
Work with time and money
MGSE2.MD.8 Solve word problems involving dollar bills, quarters, dimes, nickels, and pennies, using $ and ¢ symbols appropriately. Example: If you have 2 dimes and 3 pennies, how many cents do you have?
Represent and interpret data
MGSE2.MD.10 Draw a picture graph and a bar graph (with single-unit scale) to represent a data set with up to four categories. Solve simple put-together, take-apart, and compare problems1 using information presented in a bar graph.
OVERVIEW
In this unit students will:
• continue to develop their understanding of and facility with addition and subtraction
• add up to 4 two-digit numbers.
• use a variety of models (base ten blocks- ones, tens, and hundreds only; diagrams; number lines; place value strategies; etc.) to add and subtract within one thousand.
• become fluent with mentally adding or subtracting 10 or 100 to a given three-digit number.
• demonstrate fluency with addition and subtraction.
• understand the relationship between addition and subtraction (inverse operations).
• represent three digit numbers with a variety of different models (base ten blocks- ones, tens, and hundreds only; diagrams; number lines; place value strategies; etc.).
• recognize and use place value to manipulate numbers.
• continue to develop their understanding of, and facility with, money.
• count with pennies, nickels, dimes, and dollar bills.
• represent a money amount with words or digits and symbols (either cent or dollar signs).
• represent and interpret data in picture and bar graphs.
• use information from a bar graph to solve addition and subtraction equations.
