Grade 4 Problem of the Week (a multi-­‐step one – good luck): We all know how important it is to drink plenty of water throughout the day – whether you are a singer or not. In fact, our bodies are filled with water. Our bodies are comprised (made up of) 70 % water. Water is used by all the human systems. Children aged 9 – 11 need about 2 liters of water each day. They get water through fruits/ vegetables, and by drinking water. If you get 1 litre of water through fruits and vegetables, and have three 250mL water bottles full of water during the school day, how much more water should you drink at home? Find the difference between 2 litres and your water consumption. Answer in milliliters. Show Your Work: Prove Your Work: Draw your answer here. Hint/ Steps: st
1 – Convert 2 L to mL (remember 1 L = 1000 mL) nd
2 –Convert 1 L to mL rd
3 – Start with your total mL and start subtracting your water consumption from food and water bottles th
4 – What you have left over is how much water you still need to drink at home Weekly Skills Training Skill: Understanding Metric Conversions Play Powerama, Metric 4, Metric 5, or Metric 6 on www.mathfrog.ca for additional practice. Here is a Musical Metric Function Machine Musical Monster for linear measurement (measurements of lines). 12 mm 1.2 cm Converts millimeters to centimeters Divide by 10 IN OUT 40 mm 4 cm 100 mm 10 cm 1 mm 0.01 cm 25 mm 2.5 cm Create your own Musical Metric Function Musical Monster. Include at least four ins and outs, and a rule. Your machine may convert a unit for capacity OR mass. [See charts below] Be creative! The most interesting machines will be shared on our class website. Conversions for Capacity 1 mL = 0.001 L 1 L = 1000 mL 1 cm3 = 1 mL = 0.001 L (Volume & Capacity) Conversions for Mass 0.1 grams = 1 milligram 10 milligrams = 1 gram 1000 grams = 1 kilogram 1 hectogram = 0.1 kilogram 1 hectogram = 100 grams Problem of the Week Rubric Problem R 1 2 3 4 Skills R 1 2 3 4
