A web page and interactive applet show how to compute the length of the diagonals of a rectangle. A rectangle is shown that can be resized by dragging its vertices. As you drag, the diagonals are continuously recalculated. Text on the page explains calculation. For those who prefer it, in a formula that is given. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference interactive geometry reference book project at http://www.mathopenref.com.

An interactive applet and associated web page that demonstrate the diameter of a circle. The applet shows a circle and a diameter line, the ends of which can be dragged to show that the diameter passes through the center and has a constant length regardless of where on the circle it is drawn. The web page has the circle-related formulae. Applet can be enlarged to full screen size for use with a classroom projector.

Diane Nash was a college student when she started leading sit-in demonstrations to protest discrimination. In this interview, recorded for Eyes on the Prize, Nash describes her role in the Civil Rights movement.

This task supports students in correctly writing numbers. Because students have to trace the number, instead of coloring in a bubble with the number in it or circling the correct number, they gain handwriting practice as well as counting and addition practice.

Mrs. Crowell takes her 2nd and 3rd graders on a nature walk where they use a dichotomous key to identify different species they encounter. This lesson shows a simple way to take students out on a walk and teach them how to identify species, no matter where they are.

This is the Listening Guide for the October 14th, 2020 Read Aloud of "Dick Whittington," a story from England.

' Listen to the audio file... The first reading will be at normal conversational speed; the second reading will be slower so that you may properly [record] the sentence.

'Record your dictation in the text field...

'When you are finished, click the button at the bottom of the page to submit your finished text for automatic evaluation.

'The evaluation will check and correct your text, if needed.'

*The reading speed can be adjusted on all parts of the site where oral readings are available (mostly the Listening and Dictation exercises).*

« Ecoutez le document audio. L'orateur français effectue une première lecture du texte à une vitesse normale. Il fait ensuite une lecture plus lente, en dictant les mots.

« Ecrivez ce que vous entendez dans le champ de texte...

« Une fois que vous avez terminé, vous pouvez envoyer votre texte...

« Vous obtiendrez immédiatement la correction de votre dictée, vous pourrez ainsi repérer vos erreurs et voir votre note finale. »

*Le débit de lecture peut être réglé pour tous les extraits lus à l'oral (qui se trouvent principalement parmi les exercices d'Écoute et de Dictée).*

Use as a dictonary, to do word of the day with students or a thesaurus. It also has games.

« Le Dictionnaire des francophones est un dictionnaire collaboratif numérique ouvert qui a pour objectif de rendre compte de la richesse du français parlé au sein de l’espace francophone ... Les dictionnaires généraux du français se focalisent sur le français standard, commun, par rapport auquel les variétés sociales (argot, mots familiers, etc.) ou géographiques (belgicismes, québécismes, etc.) sont situées. Le but du DDF est de décrire dans une même ressource tous les mots du français, quel que soit la région ou le registre de langue où ils sont utilisés, pour donner accès à une image instantanée, sans cesse renouvelée, du français dans le monde ... Dans le Dictionnaire des francophones, toutes les variétés du français sont présentées ensemble et placées sur un pied d’égalité. »

On peut choisir une localisation géographique avant d'initialiser sa recherche d'un terme quelconque, ou faire une recherche générale qui puisera dans toutes les ressources numériques du DDF.

This is an activity about creating impacts on sandy surfaces. Learners will use trays of sand and a variety of solid objects to model the effects of "impactors" on the surface. This is activity 6 of 9 in Mars and Earth: Science Learning Activities for After School.

Learners will use trays of sand and cups of water to recreate surface features seen in images of Mars. This is activity 5 of 9 in Mars and Earth: Science Learning Activities for After School.

This is an activity about modeling the effect of wind on a sandy surface. Learners will use trays of sand and straws to recreate surface features of images of Mars. Participants test their ideas about how some of the features on Mars might have been produced. This is activity 4 of 9 in Mars and Earth: Science Learning Activities for After School.
