Homework Due 1-20-16

7th: Handout: practice Subtraction with Negatives

8th: How come we have to measure 2 things to get one value for “slope”? Describe the two things we measure and why these two things determine the “steepness” of a line.

Alg: Three playing cards are placed in a row, from left to right. One card is a club (♣), one card is a diamond (♦), and one card is a heart (♥). The number on each card is different. One card is a four, one card is a five and one card is an eight. Using the following clues, determine the exact order of the cards, from left to right, including the suit and number. 1. The club is somewhere to the right of the heart. 2. The 5 is somewhere to the left of the heart. 3. The 8 is somewhere to the right of the 4.

7th: Students understand the rules for multiplying and dividing integers


CCSS 
7.NS.2 Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers. a. Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts. b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then –(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real world contexts.

8th: Students understand "slope" as visual rate of change. Students find and model slope.


CCCS:
8.EE.5 Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.
8.F.A.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).

Homework Due 1-13-16

7th: Handout--

1. Moby is hanging a tire swing from a tree branch. The branch is 7 meters off the ground, the rope he’s using to hang the swing is 5 meters long, and the tire is 1 meter in diameter. How far is it from the ground to the bottom of the tire?

2. Cassie maxed out her credit card! She spent $300, when she only had $135 in her bank account. After she pays the $135 she had saved, how much more will she owe?

3. On the evening of January 12, the temperature outside was 8 degrees Celsius. Overnight, the temperature dropped 15 degrees! What was the temperature the next morning?

4. At the mall, Cassie saw a dress that originally cost $125. But fortunately for her, it was on sale for $33 off, and Cassie bought it! How much did she pay for the dress?

5. Tim went cliff diving! He jumped off a 25-meter-high cliff into a lake. At the bottom of his dive, he was 8 meters below the surface of the water. How far did he dive, from the top of the cliff to the deepest point in the water?

8th: Handout pg 58-59

Algebra: 
1. Two small pitchers and one large pitcher can hold 8 cups of water.  One large pitcher minus one small pitcher constitutes 2 cups of water.  How many cups of  water can each pitcher hold? 

2. A test has twenty questions worth 100 points.  The test consists of True/False questions worth 3 points each and multiple choice questions worth 11 points each.  How many multiple choice questions are on the test?

Math Week 1-11-16

7th: Students can readily tell when an answer to integer addition or subtraction will be positive or negative. Students can solve real-world tasks using integer addition and subtraction. Students understand the rules for multiplying and dividing integers

CCSS 7.NS.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. 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.


7.NS.2 Apply and extend previous understandings of multiplication and division and of fractions to multiply and divide rational numbers. a. Understand that multiplication is extended from fractions to rational numbers by requiring that operations continue to satisfy the properties of operations, particularly the distributive property, leading to products such as (–1)(–1) = 1 and the rules for multiplying signed numbers. Interpret products of rational numbers by describing real-world contexts. b. Understand that integers can be divided, provided that the divisor is not zero, and every quotient of integers (with non-zero divisor) is a rational number. If p and q are integers, then –(p/q) = (–p)/q = p/(–q). Interpret quotients of rational numbers by describing real world contexts.

8th: Students can find solutions to linear equations in two variables using substitution. Students will create their own linear equation tasks in the style of 3-Act Math from tapintoteenminds.com. Students begin their conceptual understanding of "slope".



CCCS: 8.EE.C.7b Solve linear equations with rational number coefficients, including equations whose solutions require expanding expressions using the distributive property and collecting like terms.

8.EE.5 Graph proportional relationships, interpreting the unit rate as the slope of the graph. Compare two different proportional relationships represented in different ways.
8.F.A.2 Compare properties of two functions each represented in a different way (algebraically, graphically, numerically in tables, or by verbal descriptions).
