Topic 7: Understanding Subtraction
Meaning of Subtraction
Throughout Topic 7, students represent subtraction using their fingers, objects, drawings, and verbal explanations. As understanding develops, students learn how to complete sentences and write equations to model subtraction situations. Students understand subtraction as "take apart" (sometimes referred to as "separate") and "take from" (or "take away").Fluently Subtract Within 5
Students begin to develop fluency with subtraction within 5 by finding patterns in subtraction facts. Seeing the part-whole relationship and finding patterns, such as if zero is subtracted from a number, the difference is that number, will help students to subtract fluently. Seeing subtraction facts for a number organized in a list helps students notice other patterns, such as the difference decreases when the number being subtracted increases.
Common Subtraction Situations
Students focus on two different types of problems in this topic: "take from: and "take apart." Students represent the problems in different ways including with objects, drawings, and equations. They see how each object, picture, or part of an equation represents a quantity in the word problem.
1st Grade Math
Topic 9-Compare Two-Digit Numbers
Students identify number patterns. They use tools such as place value blocks and the hundred chart, to help name numbers that are 1 more, 1 less, 10 more, and 10 less.
Topic 9- Greater Than and Less Than
Topic 9-Use the Symbols <,=,>
2nd Grade Math
Topic 9: Patterns and Comparing
Students learn to compare 3-digit numbers using place value. They start with the greatest place value and work towards the least place value. Then they write comparisons using the symbols >, <, and =.
Topic 10: Addition Strategies
Mental Math: Students learn to add 10 or 100 mentally. Place-value blocks and place-value understanding support the work.
Add on an Open Number Line: Students add on an open number line. They start at one addend and make jumps to match the hundreds, tens, and ones of the other addend. They also learn that they can make bigger jumps.
Topic 10: Addition Strategies (Continued)
Place Value and Partial Sums: Students use a place-value chart to record and add partial sums. Using the partial-sums strategy along with place-value chart emphasized the place value of digits.
