Division With a Remainder Sometimes when we divide into equal groups, there are some left over. If we divide cookies into groups of we have left over.. How many groups of cookies do we have? groups. How many cookies are left over? cookie When we divide, the part that is left over is called the remainder. We write the division problem like this: r number of groups and ) how many left over number of cookies in each group number of cookies all together Draw circles to divide into equal groups. Write the division problem with the remainder. The first one shows you how. Circles may vary. 3. groups of groups of groups of r ) 3 r3 ) r ) 0

2 . groups of groups of groups of 3 Lesson 3 r 3 ) r ) 5 r 3 ) We Remember Write the sums or differences. Check the last 3 problems. 5. 5, , , 0 3,0,0, 0 5 3, 3 0 0,,05 Solve Fill in the blank.. There are,000 meters in a kilometer. Underline what you would measure with kilometers.. the distance to your uncle s place in another state the distance from your house to the road

3 Lesson 3. Aunt Martha opened 3 cans of pork and beans to heat on the camp stove for supper. It made 30 ounces of beans altogether. How many ounces did each can hold? 0 ounces 0 3)30 0. Dad bought a pack of rolls of film. He could take pictures with each roll. How many pictures could he take all together? pictures * Round to the nearest 00 to estimate each answer. Then find the exact answer Estimate Estimate ,000 Add or subtract. When the fraction equals, rewrite the sum as.. = + = = = Round to the nearest dollar. 3. $. $.00 $.50 $3.00 $. $.00

Read to your teacher. = 3 of.3 3 > n + 3 = 0,503 Radius and Diameter The distance from the outside of a circle to its center is called the radius (r d és). radius diameter The distance across a circle through the center is called the diameter (d am é tßr). The diameter of a circle is times as long as the radius. When the radius of a circle is 3, you can find the diameter by doubling 3. 3 metric 3 5 Use a centimeter ruler to measure the radius and the diameter of each circle... radius diameter radius diameter

6 Lesson 3. radius diameter 3. If a circle has a radius of inches, what is the diameter? in We Remember Write yes if the shape is symmetric. Write no if it is not. 5. yes yes no Write the sums or differences , +, 3,5, 0, 3 3,, 3, Add or subtract. When the fraction equals, rewrite the sum as.. + = = + = = 5

7 Lesson. Mother had packed a total of blankets and sleeping bags into the van for camping at night. When these are shared among the Yoders, how many covers does each person get? covers ). Robert watched Old Faithful shoot hot water high into the 0 air at 0:5 in the morning. He wanted to see it again, so 5 3 Jonathan waited with him. The geyser erupted again at :05. How many minutes passed between the two eruptions? 50 minutes 0. The temperature of the air at noon in the park was 5 degrees. Look, said Sharon. This sign says the water in this hot spring is degrees. Feel how warm it is! How much warmer was the spring water than the air? degrees 0 5. The Yoder family was amazed at the beautiful waterfalls in Yellowstone Park. "This sign says that Lower Falls is nearly two times as high as Niagara!" said Jonathan. "Niagara Falls is about 0 feet high," said Dad. About how high is Lower Falls in the Yellowstone Park? 30 feet 0 * 30

8 Lesson Draw circles to divide into equal groups. Write the division sentence with the remainder. See how the first one is done. Circles may vary.. groups of 5 groups of groups of 3 5=r3 = 3r 30 = r Solve ,3 3,3 5 3,53 Do the exercises about the circles.. How many fourths are shaded? 5. Circle the shape that is divided into quarters... Fact Focus 5 3 ) )0 )3 ) = = 3 = 5 = 0 = 5 0 = 0 = = = 0 = 0
