Vocabulary Builder

Moby Vocabulary is the fastest way to learn new words and ensures that students remember words for a lifetime. The Common Core Standards specifically note the importance of vocabulary: "The importance of students acquiring a rich and varied vocabulary cannot be overstated. Vocabulary has been empirically connected to reading comprehension since at least 1925....the difference in students' vocabulary levels is a key factor in disparities in academic achievement ..."

The Find-Learn-Practice-Review Cycle

The Find-Learn-Practice-Review Cycle

Moby's adaptive pretest ensures that students only practice unknown words. Students learn each word and then practice word meanings by matching the word with the appropriate definition, sentence, and picture. The review cycle ensures that vocabulary words are retained for life.

Adaptive + Review = Speed + Mastery

Research has consistently shown that vocabulary is the key to becoming an effective reader. Students practice words they do not know and skip words they have already mastered. Using spaced-interval-training techniques, students review words frequently over a period of weeks and then over a period of months.

Easily see students' progress

Easily see students' progress

Moby constantly monitors student progress and word acquisition. You will easily be able to see your students' weekly, monthly and even daily progress. Moreover, you can monitor acquisition rates to see how fast your students acquire new words.

Create automatic or custom word lists

Teachers can opt to start students with a pretest or manually determine each student's word level. The teacher can then allow Moby to find the words the student is not familiar with or build their own word lists. Either way, the student will learn effectively and efficiently with the Find-Learn-Practice-Review cycle.

Dramatically Increase your state test scores
Help Struggling Students catch up to their grade level

Why MobyMax Works

The fastest way to increase test scores is to help students learn missing math and ELA skills. MobyMax's comprehensive learning system automatically diagnoses areas of weakness, assigns targeted lessons to improve those areas, and tracks progress as students master skills. MobyMax's test prep further improves student performance to dramatically increase test scores.

1. Find and Fix Missing Skills

MobyMax diagnostic, formative, and summative tests find missing skills. Then, Moby's adaptive curriculum creates a unique, individualized education plan for each student, ensuring that students get the instruction they need.

2. Monitor Learning Goals

Data and goals are essential for increasing scores. MobyMax shows your students' current grade level proficiency as well as how fast your students are learning. The students' learning velocity allows you and your teachers to make sure students are on track to meet their goals.

3. State Test Prep Practice

The final step in improving state test scores is state test prep. For test review, MobyMax pinpoints areas of mastery with a short review and targets areas where help is needed for more practice. The adaptive review means students do not waste time practicing material they have already mastered. Students increase their scores and confidence with just two weeks of practice and review!
