Maria's Math News, Vol. 50, February 2011
Hello again! After a busy January and start of school, maybe February is a bit more peaceful. In the newsletter there is something for everyone again, I hope! 1. Math Mammoth news 2. Games for order of operations 3. Decimals videos: tenths, hundredths, and thousandths 4. Tidbits 1. Math Mammoth newsFirst of all, Grade 1 curriculum (in Light Blue series) has been revised with more writing space. Second grade will be revised similarly.Secondly, if you're in SOUTH AFRICA please take note! A company there will publish math books based on my complete curriculum worktexts. I'm not sure exactly when yet, but I expect first grade to be available in February and then others later this year. It won't be called Math Mammoth but will have a different name and cover. I will keep you updated. Lastly, an UPCOMING SALE. Homeschool Buyers Co-op will run a group buy of Math Mammoth package products (bundles) in March. 2. Games for order of operationsIf your student or child needs more practice with order of operations, here are some online games for that. These shouldn't include integers, but just the four operations (addition, subtraction, multiplication, division) and parenthesis.Most kids just love using games and interactive quizzes for practice instead of worksheets. Click the link to find the games, and have fun! Games for order of operations
3. Decimals videos: tenths, hundredths, and thousandthsI have now been able to get back to shooting videos after a long break. These three videos (titled Tenths, Hundredths, and Thousandths) deal with what decimals are (they're fractions!) and in that sense are tied together.The first video explains about decimal numbers with one decimal digit (tenths) using fractions and a number line. I also include some easy addition problems. ![]() In the second video below, I explain decimals with two decimal digits—or hundredths—using fractions and a number line. Also included an explanation of why you can "tag" or "add" zeros to the end of a decimal and its value does not change. ![]() Lastly, I explain decimals with three decimal digits—or thousandths—using fractions and a number line. Then I show examples of converting fractions to decimals and vice versa. ![]() 4. Tidbits
