We are also learning how to round decimals to the nearest tenth, hundreths, etc. This concept was also like a review for me. I have not forgot how to round from all those years in elementary when I learned it. Decimals are usually involved when we measure things.
Yesterday, we learned how to find the volume of an object. It is also another easy concept for me. We measured objects around the classroom, wrote down the length, width, and height, and plugged in the formula. Basically, what we are learning about in science right now is mostly review. I can't wait until we perform actual experiments.
