Summary : An All-In-One Measurement App

[asa_item id=”557839389″]

My Tools—My Light & Ruler provides users with a ruler, lamp, protractor, and level. To access each of these tools, users must click the button located on the bottom of the app. With the ruler, users can choose if they want to use inches or centimeters, and they can measure items up to 7.5″ in length and 5.5″ in width. The lamp allows users to send out an SOS message, and they can choose the lamp’s color and brightness. The angle provides users with a protractor-type tool that can be used to find the degree of an angle, and users can select if they wish to use a one-prong or two-prong protractor. The level lets users judge the incline or decline of an object by laying their iPad on it.

#### Instructional Ideas

1. Teachers can have students use the ruler tool in this app as an aid to finding the area of an object. To do so, teachers can have different sizes of paper cut out that students lay on their iPad. Next, students measure the height and length of the paper to determine the area. As closure, teachers can review the different areas of the cut outs with their class.
2. Students can use the level tool to determine which objects in their classroom are flat (e.g., the floor) and which have a pitch (e.g., a student desk). After becoming familiar with the level of objects, teachers can stir conversation by asking: (1) Which objects that you would assume are level are, in fact, not level? How does that affect you? (2) How “un-level” does an object need to be before you will notice it? (3) Are some objects better off being “un-level,” such as writing surfaces?
3. Students can use the angle tool to begin familiarizing themselves with a protractor. To aid in this process, teachers can cut out objects and have students determine the objects’ angles using this app. Teachers can follow up this activity by asking students when it would be appropriate to use the two-pronged protractor versus the one-pronged protractor.
