Happy New Year! I hope everybody had a great vacation and are ready to work! Class FE7B has already started new units for both math and science! So far in math, we just recently were told that we will be starting a new unit about Ratios and Rates! A ratio is a comparison of two different numbers and are used in everyday problems and I'm sure this unit will help us all with simple mathematics skills.
Here is a problem that could occur involving ratios.
Francis decided to have a garage sale of all her old toys when she was younger. In total she had 12 dolls, 6 rubber balls, one yo-yo, and 1 set of paintbrushes. By the end of the garage sale Francis had only 3 dolls and 2 rubber balls. Francis wants to know how many items she sold.
We can use ratios to figure this problem out.
Francis had 20 items in total. She sold her yo-yo, her paintbrush set, 6 of her twelve dolls, and 3 of her 6 rubber balls. In total, she only has 9 items left of the 20. We can present this ratio as a part to whole. 9:20. In total, she sold 11 items with 9 items left over. We can present this ratio as a part to part. 9:11.
Ratios are fun and are used everyday! Class FE7B is very excited to see what we will learn in this unit!
As for science, we have only begun our unit on pure substances and mixtures so I will tell you readers next week about what we learned. Here is a safe website on pure mixtures and substances for anyone who wants to learn more about this unit. http://www.chem4kids.com
Have fun and I'll write next week!
