I can . . . order and compare integers. I can . . . write an expression to solve for the perimeter of a shape. Apply and extend previous understandings of operations with fractions. CCSS.MATH.CONTENT.7.NS.A.1 Apply and extend previous understandings of addition and subtraction to add and subtract rational numbers; represent addition and subtraction on a horizontal or vertical number line diagram. CCSS.MATH.CONTENT.7.NS.A.1.A Describe situations in which opposite quantities combine to make 0. For example, a hydrogen atom has 0 charge because its two constituents are oppositely charged. CCSS.MATH.CONTENT.7.NS.A.1.B Understand p + q as the number located a distance |q| from p, in the positive or negative direction depending on whether q is positive or negative. Show that a number and its opposite have a sum of 0 (are additive inverses). Interpret sums of rational numbers by describing real-world contexts. CCSS.MATH.CONTENT.7.NS.A.1.C Understand subtraction of rational numbers as adding the additive inverse, p - q = p+ (-q). Show that the distance between two rational numbers on the number line is the absolute value of their difference, and apply this principle in real-world contexts. CCSS.MATH.CONTENT.7.NS.A.1.D Apply properties of operations as strategies to add and subtract rational numbers. Agenda 1.) Warm Up, Mindfulness, and This Day in History What do you know Wednesday: What did you know about writing expressions before 9th grade? 2.) Math Warm Up (file on Day 13) 3.) Integer War 4.) Page 8 in notebook -- show your best work (See instructions in "Day 14" file) 5.) Writing Algebraic Expressions foldable notes (downloads at the bottom of the page at equationfreak.blogspot.com/2014/08/algebraic-expression-foldable.html) 6.) Beginning of notes (file below). No homework tonight.
