Counting Natural Numbers Less Than 1,000

Hard

(Originais Teachy 2024) - Question Hard of Mathematics

In our classroom, we have a box with several colored pencils. Upon counting, we noticed there are 23 blue pencils, 17 green pencils, and 10 yellow pencils. However, teacher Silvia challenged us to find out how many colored pencils we have in total, without counting one by one. To help solve this challenge, we can use what we have learned about numbers smaller than 1,000. Think carefully and write how you would find out the total number of colored pencils in the box, explaining what each step of your reasoning means.

In a science project, students need to measure different volumes of liquids for their experiments. The scale used to measure the volume of water can only measure in multiples of 100 milliliters. When measuring, the scale shows 450.725 grams of water. We know that the density of water is 1 g/ml. (1) Round the volume measured by the scale to the nearest milliliter. (2) Explain why the scale provided a number in grams instead of milliliters and how you used the density of water to convert the measurement back to volume in milliliters.

In Ana's lunchbox, she has 8 green grapes and 6 purple grapes. In João's lunchbox, he has 4 grapes of each color. If they combine all the grapes and divide them equally between them, who will have more grapes, Ana or João? Write two different addition equations that result in the same total number of grapes to help Ana and João divide the grapes fairly.
