Estimating the Weight of Odd Objects Worksheets

How to Estimate the Weight of Odd Objects - In a supermarket, while doing groceries, suppose that you want to purchase oranges that are sold by their weight. You see that they are sold at a rate of two dollars per kg, but you only have a dollar left. Of course, you can use a scale to weigh half a kg of oranges that can be bought in a dollar. But what if the scale is broken and making an estimation is your last resort. How will you estimate the weight of these oranges? Weight estimation is an easy technique to learn. You just have to compare the weight of an object, no matter how odd it is, with another object whose weight is known to you. For example, in this case, compare the weight of orange with that of an apple or any other object of a similar type whose weight is known to you. By doing that, you can have a closer estimate of the weight of an orange. However, before doing this, you need to have a better idea about units of measurement. Only then will you be able to judge the weights of light and heavy objects without using a device. These worksheets are filled with problems that ask students to critically think and ballpark the weight of seemingly odd objects.

Homework Sheets

I think that it is very important to show a picture of the item that we are looking for the proper unit of. It gives kids a point of reference.

  • Homework 1 - Banana is relatively light. So we are looking for a light, but not too light estimate.
  • Homework 2 - Toy horse is relatively heavy. So we are looking for a heavy, but not too heavy estimate.
  • Homework 3 - A kilogram is used to measure the weight of heavier objects. An average adult weighs about 65 kg. A tiger is heavier than your average person.

Practice Worksheets

I labeled the images that were a little obscure. Some people weren't sure if sheet 3 had a cookie or a planet.

  • Practice 1 - A gram is used to measure the weight or mass of very light objects.
  • Practice 2 - A kilogram is used to measure the weight of heavier objects.
  • Practice 3 - Choose the best estimate for the weight of the object below.

Math Skill Quizzes

For the quizzes, I made absolutely sure to choose clearly recognizable images and icons, if you will.

  • Quiz 1 - The rooster always stumps people.
  • Quiz 2 - What is the best estimate of weight for each object?
  • Quiz 3 - You know the drill by now! How much do you think they weigh?
