Vocabulary

 Inch: a customary unit of length Yard: a customary unit of length equal to 36 inches or 3 feet Foot: a customary unit of length equal to 12 inches Centimeter: a metric unit of length, about the width of your finger Meter: a metric unit of length equal to 100 centimeters Estimate: a number close to an exact amount Length: the distance from one point to another Equation: a number sentence with an equal sign, the amount on one side of the equal sign has the same value as the amount on the other side Number Line: a diagram that represents numbers as points on a line Analog Clock: a clock with numbers 1 to 12 around the face and rotating hands to show the hour, minutes, and seconds Digital Clock: a clock that uses numerals only to show the time Minute: a unit of time equal to 60 seconds Hour: a unit of time equal to 60 minutes Quarter Hour: a unit of time that measures fifteen minutes Half Hour: a unit of time that measures thirty minutes Half Past: thirty minutes past the hour Penny: a coin worth 1 cent Nickel: a coin worth 5 cents Dime: a coin worth 10 cents Quarter: a coin worth 25 cents Data: Information that has numbers Line Plot: a graph showing frequency of data on a number line Table: an organized way to list data Bar Graph: a graph that uses the height or length of rectangles to compare data Picture Graph: a graph that uses pictures to show data

Activities At Home

• Look at a TV guide and locate the time a favorite show starts. Have your child find that time on an analog clock.
• Look through an ad in the paper to locate an item your child would want (less than &10.00). Have your child count out that much money, then ask them to make change from a \$10.00 bill.
• Have your child pick out two or three items in an ad, then add the amounts together to see how much the items would cost altogether.
• Estimate the lengths of various objects around the house, such as a table, a book, a toothbrush, etc. Next, Measure the same objects using a ruler with inches and centimeters to compare the estimate to the actual length.
• Measure the four sides of a square or rectangular table using inches, and then add the four sides together to find out how long the table is around.
• Measure two different book lengths using centimeters. Compare the two lengths and determine how much longer one book is than the other.
• Give your child various amounts of money to count, using dollars, quarters, dimes, nickels, and pennies.
• Survey various family members about their favorite sport, color, ice cream flavor, or pizza topping. Create a bar graph to show the data.

(2.OA.3) Quarter 3 and 4 Use addition to find the total number of objects in rows and columns. (2.OA.4) Quarter 3 and 4

Vocabulary

 Addition: To join two or more groups. 2 + 3 = 5 Subtraction: To find the difference when two groups are compared or to find out how many are left when items are taken away from a group. Addend: A number that is added to another in an addition problem. In 2 + 3 = 5, 2 and 3 are addends. Difference: The answer to a subtraction problem. In 8 – 3 = 5, 5 is the difference. Sum: The answer to an addition problem. In 2 + 3 = 5, 5 it is the sum. Equal sign (=): A symbol used to show that two amounts have the same value. 384 = 384 Number Sentence: A sentence that includes numbers, operation symbols ( +,- ), and a greater than or less than symbol ( >,< ) or equal sign. 5 + 3 = 8 25 < 32 Regroup: To exchange amounts of equal value to rename a number. Decompose: To break a number into smaller parts to simplify computation. Example: 15 = 10 + 5. Compose: To put decomposed numbers back together. 10 + 5 = 15. Array: An arrangement that shows objects in rows and columns.

Activities At Home
