Free Elementary Math Books
Today’s Homeschool Freebie is an elementary math textbook from 1915:
The book covers the basic arithmetic from addition and subtraction to simple multiplication and division, with quite a bit of measuring and fraction work, too. The concepts are taught through stories, and then the teacher is to give the student plenty of hands-on experience with measurements. Each lesson concludes with a page of practice problems.
If you miss the daily freebie, you may still be able to get the book through Google (but I’m not sure this works if you are outside the United States):
All week long, CurrClick is offering a free “Make It Real Learning” math workbook:
The States by the Numbers series features 4th-6th grade “math adventures” about your favorite states (the freebie is Wisconsin). The workbook covers place values, rounding, estimation, fractions and percentages using data from the Census Bureau’s 2008 Statistical Abstract of the United States. The workbook includes basic instruction and 80 practice problems, plus several “What’s the big idea?” journal pages which ask learners to reflect on the things they’ve learned. You may want to let your students use a calculator, since real data often means large, unwieldy numbers.
Don’t miss any of “Let’s Play Math!”:
