![]() ![]() TI Math has companion sites in different languages and for countries all over the world. Kids receive ample help and instructions. It’s not as engaging as it could be, since kids don’t get much of a chance to personally connect with the content.Īctivities are very directed, so kids spend more time following directions than figuring things out and trying different strategies. ![]() Website: education.ti.com/en/timath/us/home For example, in “Double Tree,” learners “create” a mathematical model for a tree that doubles in height every year. However in reality they’re not creating anything - they’re simply following a set of cookbook steps that show them how to replicate someone else’s model, which doesn’t explain exponential growth in a particularly engaging or useful way. Most of them have clear directions and attempt to provide real-world context for the math problems. The activities are very straightforward and directed, providing little opportunity for kids to puzzle through or try multiple strategies. The activities themselves vary in strength. TI Math’s greatest strength is that you can find a well-organized activity quickly for any of the Common Core High School Math Standards. Teachers can search by subject, key words, standards, or textbook. You can also look through lesson ideas by course. When searching for activities this way, there’s a link for standards and textbook alignment. (Desmos is a free online graphing calculator that’s a good alternative to expensive physical calculators - which can cost $80 and up - if learners have access to computers and the Internet.) TI Math has activities aligned with Common Core Standards, but they may need to be modified to truly meet the Standards for Mathematical Practice. Problems can be sent home for homework as long as each student has access to graphing technology. Most activities are best introduced to the whole class but then worked on in pairs or small groups. TI Math provides a wide range of math activities from Algebra on up. These activities are tailored toward Texas Instruments technology, though most can be done with any graphing technology. For example, kids might be asked to create a box plot and a histogram by comparing the two and drawing conclusions, connect the coordinates of the center of the circle and the radius to the parts of the circle equation (circle equations), or calculate gateway arc length. ![]() Inequalities: Plot cartesian and polar inequalities.TI Math is a website filled with activities for Algebra 1, Geometry, Algebra 2, Precalculus, Calculus, and Statistics classes. The site is sponsored by Texas instruments, and each activity asks kids to use a graphing utility such as graphing calculators, TI-Nspire, or TI-Navigator Technology. It can handle square roots, logs, absolute value, and more. Scientific Calculator: Just type in any equation you want to solve and Desmos will show you the answer. Hold and drag along a curve to see the coordinates change under your finger. Tap the gray points of interest to see their coordinates. Points of Interest: Touch a curve to show maximums, minimums, and points of intersection. Zooming: Scale the axes independently or at the same time with the pinch of two fingers, or edit the window size manually to get the perfect window. Statistics: Find best-fit lines, parabolas, and more. ![]() Tables: Input and plot data, or create an input-output table for any function Sliders: Adjust values interactively to build intuition, or animate any parameter to visualize its effect on the graph There’s no limit to how many expressions you can graph at one time - and you don’t even need to enter expressions in y= form! Plot any equation, from lines and parabolas to derivatives and Fourier series. Graphing: Plot polar, cartesian, or parametric graphs. iPad Explore math with the fast and powerful Desmos Graphing Calculator. Sliders make it a breeze to demonstrate function transformations. Using our powerful and blazingly-fast math engine, the calculator can instantly plot any equation, from lines and parabolas up through derivatives and Fourier series. To achieve this vision, we’ve started by building the next generation of the graphing calculator. Beautiful, powerful, free math exploration! Brought to you by Explore math with Desmos! Plot functions, create tables, add sliders, animate your graphs, and more - all for free.Īt Desmos, we imagine a world of universal math literacy and envision a world where math is accessible and enjoyable for all students.
