Protractor

Even on an iPad, a protractor can be used as a tool to measure angles. Children can simply practice making acute and obtuse angles by moving the line on the screen, or they can measure the angles in objects placed on top of their iPad. Try putting traditional pattern blocks or cutout paper shapes on top of an iPad screen. There are even a few apps that let you use the camera on an iPad or an iPod Touch for measuring angles.

Graph Paper

Geometry Pad lets children draw lines and shapes on graph paper. They can plot points on this coordinate grid and even add text to the screen. This app is easy to use and includes tons of functions to try out. Educreations also lets students change the background of their screen to graph paper before they start writing.

Geoboard

Say goodbye to rubber bands! This virtual tool is perfect for elementary and middle school classrooms. Kids can simply create polygons on their geoboard to show off different quadrilaterals and triangles. They can also find the perimeter and area of each shape.

Ruler

Ruler is a neat app to try out on your iPad -- it simply turns your screen into a ruler. Students can measure items placed on their screen in inches and centimeters. They can solve perimeter and area problems with the information they gather using this virtual measurement tool. There are also apps that help children learn how to use a ruler properly.

Pattern Shapes

A neat alternative to traditional pattern blocks, Pattern Shapes from the Math Learning Center is a must-have for iPad math classrooms. In addition to moving each piece around the screen, kids can draw all over the screen to show their work. A virtually endless supply of pattern blocks at your fingertips can help students who need extra support or strategic intervention.

Clock

Whether you’re teaching elapsed time or just helping students monitor their pacing and stamina, the timer built into the clock that comes with the iPad (or one of the many comparable options) is a great addition to your classroom. It's perfect for teachers with one iPad or for children working in small groups, as they can now calculate how much time has passed or learn how to read a clock with these virtual tools.

Glossary

The Common Core State Standards stress the importance of having children use math vocabulary in written and spoken explanations of their thinking. MathTerms Glossary can help students learn definitions of different words so that they can use them appropriately. It's a great reference tool for students in a one-to-one classroom and even has Spanish language entries.

Calculator

There are lots of calculators that can be downloaded for iPads including ones that feature scientific functions. Two of my favorites include handwriting recognition technology so students can use their finger or a stylus to write a problem and see the correct answer. MyScript Calculator and MyScript MathPad are great virtual tools to have available to students who want to check their work

Online Annotations via Scrible

Annotating texts is an evidence-based literacy strategy to help students understand and navigate complex text. Annotating digitally with Scrible

Registering is quick and free, whether via Google, Facebook, Twitter, Yahoo, or your own email account. Upon registration, users should select an educator account, which allows them to create libraries where they save the annotation for future reference. Among the highlights and benefits:

• Users can share video annotations with others.

Feedback via Kaizena Shortcut

Formerly known as Kaizena mini, Kaizena Shortcut is a Google extension that allows teachers to provide actionable, detailed feedback in a streamlined fashion. Typing out feedback in Google Docs comments boxes can get cumbersome. Even limiting feedback to three or four items takes time. Also, what happens when you need to address grammar errors? With Kaizena, teachers and students can:

• Provide feedback in the form of typed comments.
• Record comments verbally so that students can hear their teacher's voice on playback.
• Insert links to grammar lessons.

Formative Assessments via EDPuzzle

Teachers of language arts and all content areas try to differentiate learning to reach a diverse group of learners by using video clips. But how do you know if students are really focusing and engaging in active learning during videos? EDPuzzle helps collect formative data that can drive instruction.

Users simply register for an account and then create classes. Each class gets its own code that students use for joining. Teachers can search and upload videos from YouTube, TED-Ed, Vimeo, KhanAcademy, and other sites. Then you create a lesson by embedding questions in the video that provides immediate formative data and allows you to check for understanding. Questions can be multiple-choice or open-ended.
