As students play, my hope is they will gain a deeper understanding of perimeter, area, and their independence. Polygraph: Rectangles At first glance, these are *just* rectangles, but many perimeters and areas have been strategically chosen. Key vocabulary that may appear in student questions includes: shaded, unshaded, fraction, part, whole, numerator, denominator, simplified, and equivalent/equal to. Designed to spark vocabulary-rich conversations about fractions and part-to-whole relationships. Edited with love by Desmos Teaching Faculty. Polygraph: Shaded Rectangles by Andrew Stadel. Then let students play again and experience the power of that formal language. We recommend you don't pre-teach that language but let students use their informal language first and then connect it to the formal language in a brief period of direct instruction. This activity helps students understand the need for a common language to describe time and to surface early ideas about that language.

Time to use the four spinner, which can produce more complex expressions.I stopped updating this resource sometime in 2018.Ĭheck out for more infoĪddress comments / suggestions about this document to or activities activities were found at, at Des-Blog’s Friday Five, and sometimes on Twitter. This is a great way to slowly introduce some algebra with just two spinners, but slowly build up over The completedĬan be clicked to reveal it, followed by theĪnswer. This mode works in a way similar to the calculate mode, but an algebraic expression is shown. When the spinners have stopped aĬalculation is revealed using their values. The first spinner is letterįollowed by spin. To view the calculation in algebraic notation clickĪlgebraic expression. You can see the way the computer calculated the result by clicking theĮxpression above the target number. Note the number is always attainable and obviously there might be more than one way to get the result. The aim of the game is to use the operators Ã,+,- to reach the number When the spinners have stopped you will see a The rule guess game is not too dissimilar to the countdown game shown on British TV. There is also an option to not allow negative numbers occuring in the The game modes use the spinner values, this means that they really require at least two spinners and the challenges are In this mode the controls to change the number of sides on each spinner are visible. For example to generate random numbers, or probabilityĮxperiments. In edit mode, you can use the probability spinner however you want. The slider max value is 12, but if you click on the number you can enter your own manually, although in practiceĥ0 is about the maximum number that visually fit on the spinner. To change the number of sides for the spinners make sure you have selected Initially six sided hexagon spinners are shown which are useful Number selector in the top right hand corner. You can change the number of spinners shown by clicking the Produce a result using addition, subtraction, multiplication and division. With the built in activities you can practice BODMAS, algebraic substitution or challenge students to find the rule to These can be used as random number generators The spinner activity can display up to four spinners.
