Sherman Elementary School                               1000 W. 52nd Street                               Chicago IL 60610                               (312)535-1757Objective:The main objective of this mini-teach is for intermediate students to learn estimation and measurement using the metric system, metric lengths, masses, and areas.Material Needed:2-3 paper plates or pie pans3-5 paper or plastic drinking straws  2 bags of marbles  3 meter sticks    cotton puffballs    large sponge    large mixing bowl or bucket    liter measuring set    centimeter graph paper    balance scale with weights    student worksheetStrategy:                              Mini Metric Olympics1.  Work in small groups (5) including a team captain.2.  There are a total of six stations with a different task at each station.    Each station should have a task card with complete instructions and    materials available.  Each group is assigned to one station.3.  Each captain may read the instructions to his team.  It is extremely    important that, before each activity begins, each student estimates and    records his/her estimate on the student score sheet.  Captains should check    all members on the team before beginning each activity.4.  After each team member performs the activity.  He/she measures and records    the actual length, mass, volume or area.                          EVENT I: COTTON BALL SHOT PUT1. Have the students predict how far they can throw the shot put and record it.2. Stand on the starting line and throw the cotton ball.  Each student is   allowed one throw.3. Measure and record the shot put.                       EVENT II: RIGHT-HANDED MARBLE GRAB          1. Estimate how many grams you can grab with your right hand.2. Grab a fistful of marbles.3. Weight them on a scale.4. Record the weight.                         EVENT III:  STRAW JAVELIN THROW1. Predict how many centimeters you can throw the javelin straw.2. Throw from the starting line.3. Measure and record.                          EVENT IV: PAPER PLATE DISCUS1. Predict, in centimeters, your throwing distance and record it.2. Throw from the starting line.3. Measure and record.                       EVENT V: LEFT HANDED SPONGE SQUEEZE1. Have a sponge soaking in a large bucket of water.2. Estimate the amount of water, in milliliters, which a student can squeeze out    of a sponge.3. Measure and record.                            EVENT VI: BIG FOOT WAS HERE1. Predict (in square centimeters) the area of your foot.2. Without a shoe, trace your foot on square centimeter graph paper.3. Calculate and record the area.     4. Cut out the footprint and put your name and room number on it. Performance Assessment:The student score sheets will have 3 columns (the estimated score, the actual score and the difference between these two scores).  After the games they should total the third column.  The winner is the student with lowest score because the scoring here was designed to measure how close their estimates are to their actual performance. 1. How many liters of water will fill your bathtub?  Draw a cartoon and record    your data.2. Select five or more containers of assorted sizes and shapes.  Can you arrange    them in order from least to greatest and predict their volume accurately?    Organize and illustrate your data. 3. Select five or more objects of various sizes and shapes.  Can you arrange   them from lightest to heaviest and estimate their mass accurately?  Organize   and illustrate your data.4. Estimate the distance of a trip to school and back home in metric units.   Draw a map to scale that illustrates how far you walk or ride to school.   You may choose to do this with a partner and do a combined map so that   you are able to make comparisons.Reference:Mathematics and Science a Solution, Illustration By Sheryl Mercier,Book I Introductory Investigation `
