## Measurement and Time - CCSS 5.MD.A.1, 4.MD.A.1, 4.MD.A.2, 4.MD.A.3

1. Area and Perimeter - You will be shown a rectangle with the dimensions labeled and you must calculate the area or perimeter. For each problem you get correct, you will receive a piece of an archeological puzzle.
2. Area Explorer - Students are shown shapes on a grid after setting the perimeter and asked to calculate areas of the shapes.
3. Comparison Estimator - Similar to Estimator but compares two sets of objects.
4. Elapsed Time - Quiz matching game.
5. Elapsed Time - Select the best answer to the question.
6. Elapsed Time - Print the recording sheet for this activity and determine how many hours and minutes pass during an activity.
7. Estimator - Practice estimation skills by determining the number of objects, length, or area.
8. Finding the Area and Perimeter of Rectangles and Squares - Lesson and activity on measuring the length and width of a variety of rectangles as well as calculating the area and perimeter of each.
9. How Many Pearls - From NOVA. You've just stumbled on a treasure chest filled with pearls and you want a quick estimate of the number, without having to count them one by one.
10. Measure it - Practice using a ruler, in inches and centimeters.
11. More or Less Estimator - Similar to Estimator activity but states a quantity and asks the user to estimate whether the set of objects is more or less than the number given.
12. Perimeter Explorer - Students are shown shapes on a grid after setting the area and asked to calculate perimeters of the shapes.
13. Platform Scales Addition - Weigh several items and find the sum in hundredths of a gram.
14. Platform Scales Subtraction - Weigh several items and find the difference in hundredths of a gram.
15. Shape Explorer - Students are shown shapes on a grid and asked to calculate areas and perimeters of the shapes.
16. Units of Mass - Scroll to the middle of the page for many quizzes on this concept.
17. Using a Platform Scale - Practice using scales like the one in a doctor's office. Five Gregs will drop on the scale, waiting to be weighed. See how quickly you can weigh them.
18. Weigh the Wangdoodles - Your job is to find the weight of each Wangdoodle using the information provided by the scales. To be successful, you will have to make sure that the weight you assign to each Wangdoodle works on each scale. This activity is a fun but challenging introduction to multiple algebraic equations.
19. What Time Will It Be? - Answer questions asking you to indicate what time it will be before or after a given time period.
