division, including the placement in the estimation of the answer.
 * CFU 0506.2.7** Understand the placement of the decimal point in calculations of multiplication and long


 * ISTE NETS Creativity and Innovation 1c**. use models and simulations to explore complex systems and issues.

=**Lesson**=
 * 1) Open Kidspiration 3.
 * 2) Click on MATH VIEW.
 * 3) Checkmark the box beside USE STEPS.
 * 4) Click on BASE-TEN pieces.
 * 5) Click NAME, type name information, and click OK.
 * 6) Click Place Value Mat button from the bottom toolbar [[image:Kid3-WorkmatButton.jpg]] one time to show the "Hundreds, Tens, Ones" chart.
 * 7) Delete and retype the labels in the box at the top of the page to show, "Ones, Tenths, and Hundredths". (Simply click on the label's space to see the text cursor.) The flats will now model whole Ones. The rods will model tenths. The units will model hundredths.
 * 8) Click and drag a text box from the left hand toolbar to the space between the "Ones" and "Tenths" labels to show correct number place value.
 * 9) Begin with a simple multiplication problem, such as 0.8 X 3 = . Click and drag a text box to the bottom of the step to type the math sentence.
 * 10) Click the "Resize Manipulatives" button [[image:Kid3-ResizeMedium.jpg width="50" height="40"]] in the bottom toolbar to resize the base ten pieces to small. [[image:Kid3-ResizeSmall.jpg width="48" height="35"]]
 * 11) Click and drag the number of rods to model 0.8.
 * 12) To multiply, click and drag a selection box around the 8 rods, then click EDIT and COPY from the menu. Click in the "Tenths" box, then click EDIT and PASTE to make another group of 8 rods. Repeat until the number of groups of rods equals the second number in the addition sentence.
 * 13) Click and drag a text box to the "Hundredths" box, stretch it. Type a brief reflection of what was done in that step.
 * 14) Click the ADD A STEP button from the top toolbar. [[image:Kid3-AddStep.jpg width="60" height="46"]] All the manipulatives will be instantly copied and pasted into the new step by Kidspiration 3.
 * 15) Click and drag a selection box around 10 rods. When the GROUP button [[image:Kid3-RegroupLight.jpg width="60" height="58"]] from the bottom toolbar lights up[[image:Kid3-RegroupDark.jpg width="52" height="50"]], click on it to regroup 10 tenths into 1 whole. Repeat as needed until there are less than 10 rods remaining in the tenths box.
 * 16) Click and drag a text box to the "Hundredths" box, stretch it. Type a brief reflection of what was done in that step.
 * 17) Click the ADD A STEP button from the top toolbar. [[image:Kid3-AddStep.jpg width="60" height="46"]] All the manipulatives will be instantly copied and pasted into the new step by Kidspiration 3.
 * 18) Click and drag the 2 wholes into the "Ones" box.
 * 19) Click and drag a text box to the "Hundredths" box, stretch it. Type a brief reflection of what was done in that step.
 * 20) Click and drag a text box from the left hand toolbar to the space between the "Ones" and "Tenths" labels to show correct number place value.
 * 21) Click and drag a text box from the left hand toolbar to the space between the "Ones" and "Tenths" labels at the bottom of the step to type the number answer correctly.
 * 22) In the 4th step, delete the base ten pieces.
 * 23) Click and drag a text box to the "Ones" box, then click on the OPEN MATH FRAME button [[image:Kid3-OpenFrame.jpg]]from the bottom toolbar.
 * 24) Click on that text box until you see the red and white selection boxes around it., then EDIT and COPY.
 * 25) Click EDIT and PASTE to paste one identical text box above and one identical text box below the original. Click and drag to line up the math frames vertically.
 * 26) In the center, type the math problem modeled above.
 * 27) In the appropriate boxes in the math frames above and below the math sentence, type the numbers in the answers and the numbers regrouped. [[image:Kid3-DecimalMultiplied.jpg width="117" height="192"]]
 * 28) Count the number of decimal places in the math sentence and count the same number to place the decimal point correctly.
 * 29) Repeat as time allows.

To Print to our networked printers,
 * 1) Click FILE and PRINT.
 * 2) Choose LAYOUT from the center drop-down menu.
 * 3) Change PAGES PER SHEET from 1 to the number needed to best print using the least number of pieces of paper. Kidspiration prints 2 steps per page. (Our lesson has 4 steps, so far. To print them on one page, select 2 instead of 1 page per sheet.)
