About Sentence Ninja

A high quality, value for money app. It will not disappoint and teaches kids all about how words affect sentence structure. We enjoyed playing with it and, most of all, our children enjoyed using it. We have awarded the app an EAS Certification of 5 Stars and EAS Recommended Status. 

Teacher Review

'Sentence Ninja' is a user friendly and appealing app, which is designed to develop children's ability to build sentences and develop sentence structure skills.  It starts from the most basic subject and verb structures through to complex sentences and is therefore, suitable for use with Early Years upwards.  The banks of sentences and the 39 different levels mean that this is an extensive and detailed app which can be used frequently by the same child as they progress through the various stages.

The landing page is vibrant and engaging and there is a video tutorial which allows any teacher/parent to gain an overview in how to use the app and set it up for first use.

Before starting  a parent, teacher or the child themselves add players and a photo or an avatar can be used to assist with identification.  Several players can be set up on one device and the app can be played as an individual or with multiple players.  Each player can be started on any of the 39 levels and this can be modified before starting any session. The players act as ninjas placing words into the correct sequence to create a pathway which they can then cross. The players take it in turns and each can work at his or her own level of difficulty.  Hints can be given in terms of the first word in the sentence and colour coding of the words and corresponding sentence sequence can be turned on or off as required. Once a level is completed the child can choose to try more or move on to the next level.

The 39 levels are organised into six groups and as the player completes each group, they are awarded a coloured belt.  The belts, as well as progress charts and reports, offer feedback to the child and any adults as to achievements and areas for development.  In the 'Award Centre' the progress and achievements are shown for each player and the level currently being used can be adjusted. There is also an option to open, email and print corresponding homework sheets. 

A particular strong aspect to this app is the number of settings that can be changed to meet the individual needs of the user.  Key settings include turning the audio on or off, requiring sentences to be recorded by the player once completed and modifying the exercises by  selecting which  sentences are used  within each level.  This final option is particularly useful for British users who wish to avoid Americanisms such as 'pajamas' and 'popsicles'.  Personally the only missing option is a prompt to check if players wish to quit when pressing 'Done' as often my children pressed this by mistake once completing a sentence and then had to restart the exercises.  It may also be useful if a password was required before modifying the level so that children would only able to use the exercises selected by an adult.

Overall 'Sentence Ninja' is an engaging, detailed and progressive app which can be used by children with a range of ages and abilities either independently or, as a multiplayer.   The reward system and progress charts provide positive reinforcement for the child and useful monitoring for any adults.  The range of settings means that the app can be used independently and is a great method for developing children's grammar through engaging and meaningful activities.

Sentence Ninja is a multi-player multi-level app designed to improve sentence structure skills in children and adults. Designed by a certified speech-language pathologist, Sentence Ninja uses a fun Ninja theme to engage clients in their learning while teaching word order. Easily customizable to fit nearly every need, Sentence Ninja is a great addition to the therapy toolbox.

Created to facilitate an understanding of how correct word order impacts sentence structure, Sentence Ninja has 39 levels ranging from simple phrases to complex sentences. Each phrase or sentence has a corresponding picture. Sentence Ninja is designed to teach and reinforce the grammar rules of the English language for children, English language learners, and adults requiring rehabilitation.

When playing Sentence Ninja, the active player is depicted by a ninja figure walking across stepping stones. Players waiting to take their turn are depicted on the side of the page. With each turn, a new picture is displayed with the phrase or sentence words shown on various pieces of paper. The player will drag the words, in order, to the sentence strip at the bottom of the page. If the sentence is not correct, the words will return to their position on the picture. When done with the session, a simple tap on the done button brings the user to the reports center.

From the report center, a tap on the avatar of the client brings up the choice of report cards or awards and points. The awards and points center is a great way to help clients see the scores and any awards they have won throughout the game. Report cards are kept for each session and available to track progress monitoring over time. Sentence Ninja also includes several worksheets of various skill levels that are easily printed or emailed.

Sentence Ninja has many customization choices from the “select a player” screen and from within each target page. The facilitator can choose to record the students saying the sentences, display hints, automatically increase in complexity, or turn on color coding cues. In addition, the facilitator can select the “customize word list” to select/deselect item choices.

Sentence Ninja has the following features:
•39 levels of increasing difficulty and skill levels
•Up to 5 players
•Receptive and expressive Language skills
•Data Collection over time for each student
•Compatibility with Therapy Report Center for easy report writing and progress monitoring
