Pattern Mini Lesson covers: OH Grade 4, Math StandardPatterns, Functions and Algebra 2 Represent and analyze patterns and functions using words, tables and Patterns OH Grade 4, Math StandardPatterns, Functions and Algebra 3 Construct a table of values to solve problems associated with a mathematical relationship. OH Grade 4, Math StandardPatterns, Functions and Algebra 4 Use rules and variables to describe patterns and other relationships.

Patterns- Mini Lesson 1 Number Patterns When finding the missing number in a list of numbers, you need to figure out what pattern exists in the list. First, figure out whether the numbers are increasing or decreasing. Then, figure out how much more or how much less each number is than the previous number. Here are some common patterns: 1. Sometimes the numbers increase by 1. Example: 10, 11, 12, ?, 1413 is the missing number. 2. Sometimes the numbers decrease by 1. Example: 40, 39, 38, ?, 3637 is the missing number. 3. Sometimes the numbers increase or decrease by more than 1. Example: 4, 8, 12, 16, ? 20 is the missing number.

Geometric Patterns When finding the missing picture in a list of pictures, you need to figure out what pattern exists in the list. First, look at the increasing or decreasing in the number of objects in each picture in the list. Then, figure out how much bigger or how much smaller each picture is than the previous picture. Here are some common geometric patterns: Sometimes the pictures increase by a certain amount. In this case, the number of rectangles increases by 1. The next picture in the pattern would have 4 rectangles. It would look like this: OK- Now let’s try some pattern work!-

Patterns Mini Lesson 1 Question 1 What is the rule for the pattern to the left? Click the letter to choose. A.A. Each picture in the sequence is 2 less than the previous number. B.B. Each picture in the sequence is 1 more than the previous number. C. C. Each picture in the sequence is 1 less than the previous number. D. D. Each picture in the sequence is 2 more than the previous number.

GREAT JOB The pattern should be consistent from diagram to diagram. Diagram 1 contains 3 x's. Diagram 2 contains 4 x's. Diagram 3 contains 5 x's. Diagram 4 contains 6 x's. Therefore, each diagram contains 1 more than the previous diagram. Click arrow to go to Question 2

Patterns Mini Lesson Question 2 If the pattern above continues, how many purple squares will there be in diagram 4? Click on your choice. A.A. 12 B.B. 18 C. C. 6 D. D. 10

YEAH!! The pattern should be consistent from diagram to diagram. Diagram 1 contains 36 purple squares. Diagram 2 contains 30 purple squares. Diagram 3 contains 24 purple squares. So, each diagram contains 6 purple squares less than the diagram before it. So, diagram 4 would contain 18 purple squares because = 18. Click the arrow to go to question 3.

Nope- TRY AGAIN! Click arrow to go back.Click arrow to go back. Go Back

Patterns Mini Lesson Question 3 How many flowers total are planted in 6rows? Click your choice. A.A. 35 B.B. 36 C. C. 33 D. D ?42 Number of Rows Flowers

YOU ROCK!! Flower totals increase by 6, so in 6 rows, there are 36 total flowers.

Counting Money Mini Lesson covers: OH Grade 4, Math StandardNumber Sense 8 Solve problems involving counting money and making change, using both coins and paper bills.

Counting Money It is important to be familiar with the United States coins and values. Also, it is important to be able to calculate the change one should receive from a purchase. Penny (1¢ or $0.01) Nickel (5¢ or $0.05) Dime (10¢ or $0.10) Quarter (25¢ or $0.25) Example: Question: Joe gives the gas station clerk $5 for $4.37 worth of gas. How much change should Joe receive? Answer: $ $4.37 = $0.63 or 63¢ 63¢ = 2 quarters + 1 dime + 3 pennies

Counting Money Mini Lesson Question 1 Peter bought an apple for 41¢ and a carton of orange juice for 57¢. Which set of coins would have given Peter the correct amount to pay for his apple and juice? Click on your answer. A. 2 quarters; 3 dimes; 2 nickels; 3 penniesA. B. 2 quarters; 3 dimes; 3 nickels; 3 penniesB. C. 2 quarters; 3 dimes; 3 pennies C. D. 2 quarters; 3 dimes; 2 nickels; 2 penniesD.

First, find the total that Peter paid for his apple and juice: 41¢ + 57¢ = 98¢. Next, figure out which set of coins would have given him exactly 98¢. He could have paid with 2 quarters, leaving 48¢ left to pay because 98¢ - 50¢ = 48¢. He could have paid with 3 dimes, leaving 18¢ because 48¢ - 30¢ = 18¢. He could have paid with 3 nickels, leaving 3¢ because 18¢ - 15¢ = 3¢. Finally, he would have used 3 pennies to pay exactly 98¢.

OOPS! I think you’d better try again!! Go Back

Counting Money Mini Lesson Question 2 Tony bought a video game for $6.36. He gave the clerk a $10 bill. How much change should he receive? Click you answer. A. A. 3 dollar bills, 2 quarters, 2 nickels, and 1 penny B. B. 4 dollar bills, 2 quarters, 2 nickels, and 4 pennies C. C. 2 dollar bills, 2 quarters, 2 nickels, and 3 pennies D. D. 3 dollar bills, 2 quarters, 2 nickels, and 4 pennies

YIPEE!! To figure out how much change he will receive, subtract the cost of the video game from $10.00: $ $6.36 = $3.64 Next, you need to figure out what kind of bills and coins he will be receiving. Because $3 is under $5, he will receive 3 dollar bills. For coins, because $0.64 is over $0.50, but under $0.75, he will receive 2 quarters, which leaves $0.14. Next, he will receive 2 nickels (or 1 dime), which leaves $0.04. Since $0.04 is all that is left, he will receive 4 pennies.

OH MAN! Go Back and Try Again!

Measurement Mini Lesson will cover: OH Grade 4, Math Standard Measurement 6 Write, solve and verify solutions to multi- step problems involving measurement. Standard Number Sense 7 Recognize that division may be used to solve different types of problem situations and interpret the meaning of remainders; e.g., situations involving measurement, money.

Measurement Mini Lesson Minutes are marked on a clock by the short lines that go around the entire clock face. Each line represents one minute. Hours are marked by the numerals. One-fourth (one-quarter) of an hour is 15 minutes long. Examples: The clock on the right displays a time that is three hours and five minutes later than the clock on the left.

Measurement Mini Lesson These clocks display “quarter- hours.” The clock on the left shows “quarter to” the hour, and the clock on the right shows “quarter after” the hour. The clock on the right displays a time that is 20 minutes earlier than the clock on the left.

Measurement Mini Lesson Standard liquid measurements are given in cups, pints, quarts and gallons. There are 2 cups in a pint, 2 pints in a quart, and 4 quarts in a gallon. Examples: 2 cups are equal to 1 pint. 2 pints are equal to 1 quart -- and so are 4 cups.

Measurement Mini Lesson The perimeter of an object is the total distance around all sides. Example: The perimeter of this box is 30 inches. ( = 30)

Measurement Mini Lesson Temperature measured in Fahrenheit degrees is higher than when measured in Celsius. Weight measured in pounds is a higher number than weight measured in kilograms. One pound is about the same as half a kilogram. Example: A 10-pound bag of sugar is about 5 kilograms. A backpack that weighs 2 pounds equals about 1 kilogram.

Measurement Mini Lesson Question 1 Jim mows his neighbor's lawn every 2 weeks. Since the lawn is so large, he does it over a period of 3 days. If Jim mows an area of 300 square yards every day, what is the area of his neighbor's lawn? Click the best answer. A. A. 600 square yards B. B. 900 square yards C. C. 1,200 square yards D. D. 1,800 square yards

HOORAY Since Jim mows the same amount each day and does so for 3 days in order to finish mowing the lawn, multiply the area Jim mows each day by 3 to find the total area of the lawn. 300 square yards per day × 3 days = 900 square yards

Measurement Mini Lesson Question 2 You get an allowance of $5.00 a week. If you save the entire amount each week, how many weeks will it take to save enough money to buy a game that costs $13.50? A. A. 5 weeks B. B. 3 weeks C. C. 6 weeks D. D. 4 weeks

GROOVY DUDE In three weeks you will have saved $15 (3 x $5.00 = $15). This is more than you need, but saving for two weeks gives you only $10, which isn't enough.

Measurement Mini Lesson Question 3 How many degrees has the temperature risen (in Fahrenheit degrees) between the first reading and the second? A. 25°F B. 30°F C. 20°F D. 15°F

WONDERFUL!!! Fahrenheit temperature is read on the top of the scale (indicated by °F). Each vertical line on the thermometer represents 5 degrees. The temperature has risen from 60°F to 85°F, which means the temperature has risen by 25 degrees.
