This free printable worksheet was created to be used when teaching multiplying decimals. To use the lattice method, we draw a grid and write the digits in the numbers to be multiplied along the top and down the right side of the lattice. With decimals less than 1, however, this symbol could best be replaced with the word of. It can also be shown in an area model (box) as a shape divided equally into 5 rows and 2 columns (phrased as 5 by 2).

We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.įor free. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We tackle math, science, computer programming, history, art history, economics, and more. The fun must not stop! (Content was selected for this grade level based on a typical curriculum in the United States.)Ībout Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. You can model addition and subtraction of decimals using 10 × 10 grids. As always, we'll round this out with a healthy dose of applied word problems and explorations of number patterns and properties (including the ideas of factors, multiples and prime numbers). Some of the foundational concepts of geometry (like lines, rays and angles) also get introduced. On other fronts, you'll learn how to convert between different units (which is super important when comparing the size and speed of robot unicorns in different countries) and continue your journey thinking about various shapes in two dimensions. For the fraction part you can write 2 3/100. You'll also see how they relate to decimals. You can write 2.03 for the decimal part as there is 2 wholes and 3 hundredths. Now you'll start adding, subtracting, multiplying, and comparing them. In 3rd grade you learned what a fraction is. You'll also discover that you sometimes have something left over (called a "remainder") when you divide. Not only will you be a multi-digit addition and subtraction rockstar, but you'll extend the multiplication and division that you started in 3rd grade to several digits. Grade 4th on Khan Academy: 4th grade is the time to start really fine-tuning your arithmetic skills. Practice this lesson yourself on right now: Deepen your understanding of decimal numbers by thinking about grid diagrams. State the fraction (tenths or hundredths) that is equivalent to a given decimal.
