As many of you are preparing for school work again, please take note (and bookmark!) these comprehensive worksheet lists that include most math topics for any given grade: Grade 1 Grade 2 Grade 3 Grade 4 Grade 5 Grade 6 Grade 7 Best of all, the worksheets are free! They are dynamically generated so you get a different one every time you click on the link. You can also save them to your device and edit them in your favorite word processor. Also, I recently formatted the above pages so they look good on mobile devices.

I have a new book to add to the Blue Series collection of worktexts: Math Mammoth Add & Subtract 4 Math Mammoth Add & Subtract 4 covers the following addition and subtraction related topics which are approximately for the third and fourth grade level: * mental addition and subtraction strategies; * adding and subtracting in columns; * Roman numerals; * the connection between addition and subtraction, missing addend problems, and solving word problems with bar diagrams; * order of operations; * bar graphs, line graphs, and money problems. Price: $5.00 Buy now Samples pages include: Contents and Introduction Addition Review Adding Terminology and Practice More Subtraction Review Subtract in Columns Word Problems and Bar Diagrams Rounding Line Graphs

I haven't blogged for a while but I've been thinking about this topic for a little while now. It is your multiplication algorithm, also called long multiplication, or multiplying in columns. I also happen to be writing a lesson about it for my upcoming LightBlue series 4th grade book . The standard multiplication algorithm is not awfully difficult to learn. Yet, some books advocate using so-called lattice multiplication instead. I assume it is because the standard method is perceived as being more difficult. But let's look at it in detail. Before teaching the standard algorithm, consider explaining to the students multiplying in parts , a.k.a. partial products algorithm in detail: To multiply 7 × 84, break 84 into 80 and 4 (its tens and ones). Then multiply those parts separately, and lastly add. So we calculate the partial products first: 7 × 80 = 560 and 7 × 4 = 28. Then we add them: 560 + 28 = 588. If you practice that for one whole lesson before embarking on the actual...

I spent this last Saturday working on an idea that I probably should have done a long ago... making better use of my various worksheet generators. I created a single page that has pre-made worksheets for 4th grade math . It's just long list of links, each of which generates a certain kind of worksheet. Should be handy for my visitors. So these are still randomly generated, each time it's a new one. Just hit 'refresh from the browser and a new one is there. And while building that page, I also fixed a few litte things in the generators, and added a few more options... For example, Fractions worksheet generator now has the option to make missing addend/factor/dividend sheets. So hopefully with these changes they will better serve my visitors. And yeah, I can hear some asking, "When are you going to do a similar page for 3rd or 5th grade?" Well, I hope get such done before the year is over. We will see! I DO hope to get those done as well!

Just tonight... I got my Math Mammoth grade 4-A and 4-B workbooks ready and available online. One of them is $5.50 and the other is $5... I've truly put a lot of effort on those so I hope the worksheets serve well those who buy them. They're mostly designed for teachers, but I've had homeschoolers buy the other grades so I guess they're for whoever needs a 4th grade math workbook or worksheets. You can download sample sheets here .

I'm going to talk again about the new report released by NCTM, Curriculum Focal Points. For each grade, it describes THREE focal points, and also explains to which other mathematical topics these focal points connect to. By familiarizing yourself with these few points, you can see the basics of school mathematics unfold before your eyes. Knowing the basic goals is essential for being a good teacher. By the way, these aren't the only things kids might study on a given grade. They are the focus areas. Many of the other topics would connect with these. Go look at the pics at textsavvy.blogspot.com about the way textbooks and programs typically present the topics, versus a "VISION OF CURRICULUM" laid out by the Focal Points document. On grade 1, the focus is on addition/subtraction : basic basic addition facts and related subtraction facts. Learning to add and subtract two-digit numbers. Understanding whole numbers in terms of tens and ones Composing and decomposing ...
