Place Value Practice
4th Grade
Objectives Number & Operations in Base Ten Reading and writing multi-digit whole numbers in number, name, and expanded form Comparing two multi-digit numbers based on meanings of the digits in each place, using >, =, and < Materials Needed Large number cards Place Value Playoff game mat Place Value Playoff number tiles Construction paper Scissors Chart paper (optional) Preparation: Print out the large number cards, photocopy them onto construction paper and cut them out. You will need two or three copies of each number. Introduction/Review Write 347 and 453 on the board. Ask students to tell you which number is greater. Then ask, “Which place value did you compare to know that this is true? Why?” Guide students to understand that they compared the hundreds place because it is the highest place value in both numbers. (For older students, bring up the level by writing 3,470 and 4,532 or 34,705 and 45,320.) Reinforce the concept by underlining the hundreds place in each number and telling students that four hundreds is greater than three hundreds. Now ask, “What if the numerals in the hundreds place are the same? Which number is bigger, 347 or 353?” Guide students to understand that they should compare the next highest place value—the tens place.

Multiplication Mania
3rd Grade
Objectives Students will find the product of a single-digit number and a double-digit number. Students will understand how rearranging the numerals affects the product of a single-digit number and a double-digit number. Materials Needed Baseball number cards template Multiplication Mania reproducible Scissors Introduction Write the problems 23 x 9 and 93 x 2 on the board. Ask students, “Do you notice anything similar about these two problems? Yes, they both use the same numerals but in different places.” Invite students to make a guess as to which product will be greater. Give them time to find the answers (23 x 9 = 207 and 93 x 2 = 186). Then ask students if they can think of different ways to arrange the three numerals so that the product would be greater than 207 or less than 186. Invite students to use a pencil and paper to work out some possible problems and their answers (such as 39 x 2 = 78, 29 x 3 = 87, 92 x 3 = 276 and 32 x 9 = 288).

Materials Needed Cardboard box or posterboard, cut into an outline of a bus (optional) Whiteboard or chart paper Tim’s Yard Work flyer Neighborhood Jobs reproducible Neighborhood Jobs Answer Key Preparation Print out a copy of the Tim’s Yard Work flyer and the Neighborhood Jobs reproducible for each student in your class. (You can also display the flyer on a document camera.) Introduction Instruct students to listen very carefully to the following story problem: Mr. Smith is driving a bus. At first, the bus has no passengers. At the first stop, 10 passengers get onto the bus. At the second stop, 2 passengers get off the bus. Then 4 passengers board the bus. At the third stop, half the passengers get off the bus. Pause for a few seconds. Then ask, “Now...what is the name of the bus driver?” Most students will likely react with surprise at this question, but a few will remember that you stated who was driving the bus at the beginning of the story problem. Affirm that the name of the bus driver is Mr. Smith. Ask students to raise their hands if they were calculating the number of passengers getting on and off the bus. Explain that, although this story problem was a riddle with a surprising twist at the end, those with their hands raised were actually calculating a multistep math problem that involved addition, subtraction and even division. Point out that this exercise is also a good example of why it is helpful to read the whole problem first in order to find out what information is needed to answer the question.

Friction Fun
4th Grade
Objectives Students will understand Newton’s First Law of Motion. Students will understand friction’s effect on moving objects. Materials Needed “What Is Friction?” information page and experiment sheet Books Sandpaper (one strip, approximately 4" - 5" long, for each group) Tape measure (one for each group) Toy cars (one heavier car and one lighter car for each group) 2" x 4" wood boards (each approximately 6" long for each group) Introduction Explain to students that Newton’s First Law of Motion states that an object at rest will remain at rest and an object moving in a straight line will continue to move in that direction unless an outside force interferes. Demonstrate this by setting a toy car down on a table. Ask, “Is the car moving?” (no) Reinforce that it will not move until an outside force moves it. Then push the car gently with your finger to make it roll forward, and ask students to explain what happened. (The car rolled forward because it was pushed.) Point out that the car eventually stopped rolling because it encountered friction. Tell students that friction occurs when two surfaces rub against each other. In this case, the wheels of the car rubbing against the surface of the table eventually slowed the car’s movement and caused the car to stop. In addition, heavier objects, or objects with more mass, create more friction when they come in contact with another object or surface.
