PrepositionBuilder™ is designed to help elementary aged children learn the correct use of prepositions and learn how prepositions can change the meaning of a sentence.

During play, the student is presented an image and must drag a preposition to complete a sentence about the image. If the student chooses the wrong answer, the image and sentence change to show the student the proper use of the preposition they chose and how it changes the image. Once a student completes a module, they unlock a short animation that is part of a larger story. They must complete all the modules to see the entire story.

PrepositionBuilder™ offers a rich and fun way for all students to learn proper preposition use.

- Simple and intuitive drag and drop interface to build sentences.
- 9 preposition modules including the 28 most common prepositions
- 300 images to build sentences around
- Record feature allows students to record completed sentences in their own voice
- Recordings can be archived and emailed for later play
- Each student has their own archive page
- Optional correct sentence audio re-enforcement
- Statistics to track individual students progress
- 11 animations for the student to unlock during play. Each animation tells part of a larger story.

Great app for teaching prepositions!

PrepositionBuilder™ is a fantastic app to teach children a wide variety of prepositions. You can choose from 9 different modules, each of which target 3 specific prepositions. The app uses fun cartoon pictures to depict each sentence, including the preposition, and children need to select the correct preposition, then drag and drop it into the sentence. This app supports multiple users, and has options for turning off audio instruction and correct answer reinforcement. There are no ads or social links. My son enjoys learning with Mobile Education apps, so he was a little disappointed that he had to wait through an entire module (about 21 questions) for a reward animation. I would like to see the ability to change the frequency of the reward animation in settings, as it is in several other apps by this developer. I do recommend this app though.

Another great app by the Mobile Education Store!

This is a great app and will be quite useful for those children who need help in the area of language and constructing proper sentences in regardings to using the correct prepositions. The app is very easy to use and there are nine different preposition modules available. One great feature is that there is immediate, corrective feedback. If a child answers a question correctly, there is positive reinforcement as the correct answer is stated again. If a child answers incorrectly by not choosing the proper preposition to be in the given sentence, then the image under the sentence is actually changed to represent the sentence using the incorrect preposition that the child has just chosen. This is very brief, but is great because it shows the child why his or her answer was not correct and how it affects the meaning of the sentence. Several profiles can be stored in app so that more than one child can use the app. In addition, the data in the profiles can be saved for the student(s) and reports can be formed with the data in order to track the progress of the student. Great app to use for language skills!

Awesome app for kids with autism

Preposition Builder makes use of errorless teaching and applied behavior analysis methodologies to teach and evaluate understanding of prepositions. Like other Mobile Education Store apps, Preposition Builder can keep track of progress of multiple students in a class. Prior to starting an exercise, the teacher (or student!) can choose which prepositions are being evaluated, and whether or not to record the student’s voice reading each sentence. A series of short story animations can be unlocked with each completed section. This provides incentive for students to complete the exercises so that they can find out how the story ends.

To provide documentation of student progress, Preposition Builder allows reports to be emailed to students or teachers. My only recommendation for future updates to this program would be the ability to email progress reports for ALL students (or perhaps an option to print?). Depending on the number of students in a class, it can become tedious sending individual records for each student.
