This revision should hopefully help on Chapter 3 before the exam! Now let's get going! Generating number and Spatial patterns



a. Draw the next two shapes in the pattern.b. Count the number of matches needed for each shape and write the pattern created by these numbers. <span style="color: #ff0000; display: block; font-family: Georgia,serif; font-size: 160%; text-align: center;">Explanation: Draw the next two numbers.Count the number of matches needs to make each shape.Now let's see if you were paying attention... <span style="color: #f4a91f; display: block; font-family: Georgia,serif; font-size: 160%; text-align: center;">1. Start with 4 and add 3 each time.Ans.4,7,10,13,16 2. 4000_,1000,500,_,_Ans. 2000,250,175 Example 2: Describing Spatial Patterns a. Number of matches=number of counters+3 (Use m for the number of matches and c for the number of counters) Explanation: use the given pronumerals m=c+3 Question time! 1. Number of counters=number of matches + 2 Ans. C=M+2 2.

a. draw next two shapes in the pattern. Copy and complete this table Example 3: Using rules and tables! a. multiply each number by 2b. Rule: y=(x*2)+1 Explanation: Out=In*2+1 OK, let's recap!1. Rule: Add 1 to each number

Example 4 OK now this is the last one then we are officially FINISHED!

A chocolate maker sells her delicious chocolate to the local cafe for $8 more than it takes her to make.The chocolate maker sells the chocolate to her customers for twice for what she pays them.The cost of dollars are shown on the diagram below. Chocolate maker cost+5chocolate cafe cost*2customer cost  a. Complete the following rule:   customer's cost=(chocolate cost+___)*___   b. write the rule using pronumerals   c.If a chocolate heart cost $8 to make, how much will it cost to pay for it? OK THIS IS THE VERY LAST QUESTIONED IN THIS WHOLE ENTIRE THING SO YEAH!

1. A snow cone maker makes snow cones all day long at the summer beach for $2 more than it takes her to make. The snow cone maker sells snow cones to his customers twice for what she pays them. Ans.Customer cost=(snow cone maker+2)*2write a rule using c for customer's cost and s for the snow maker's cost.If a triple snow cone cost the snow cone maker $8 to make, how much will a customer at the beach pay for it? Ans. C=(S+2)*2C=(8+2)*2=10*2=20  Explanation: The snow maker sells the snow cones to the summer beach for $2 more than his cost. The summer beach sells then for twice what they pay for. Write the rule using pronumerals. Snow cone maker cost $4, so S=4

Now we have FINISHED! :)
