Zearn Math Review
Zearn Math is a curriculum developed originally through EngageNY which created Common Core Standards and are used in the State of California under the standard called Eureka Math. It personalizes teaching and math content with are aligned to Common Core standards and grade level. It is developed to each individual grade level assigned by the teacher. Each student is working toward bettering their mathematical knowledge, not working toward a grade score. The program is designed to help students’ math fluency. Since the program is strictly designed within Common Core standards, it meets K5 requirements of:
 Making Sense of Problems students are able to view their strengths and through following a module path, if understanding is struggling, students can be moved to different level difficulty to master.
 Reasoning abstractly and Quantitively students are given the ability to make symbolic representations of numbers, compute them and reference them to what is happening.
 Students are able to critique the reasoning of others by participating in Sprint simulations where students race against each other to solve problems within a certain period of time. They are also given the opportunity to interact with their teacher as a classroom to go through module lessons that align with their daily curriculum work.
 Students are also able to construct mathematical arguments by use of symbols, graphs, diagrams to understand the conceptualization of the math problems being presented.
This program is recommended for instructional use and is already being implemented. It is also recommended for practice at home, as practice helps students retain classroom learning. The advantages for classroom use are that there is reinforcement of Common Core standards used for K5 students. For example, it follows the requirements for Grade 3, Operations and Algebraic Thinking as outlined in California Common Core State Standards in Math. Students learn how to multiply whole numbers, and divide, while also seeing the relationships between division and multiplication with deconstruction of each. Students are also exposed to the relationships with operations and explaining patterns of mathematics. Each individual module throughout Zearn covers the same outline as the standards to align the product with the exact standard, by grade level and by areas of emphasis. Grade 3, Number and Fractions outlined on the standard, is a full interactive lesson on Zearn filled with game play, number manipulation and rewards titled “Wild Cards” students can collect to show achievements. Each lesson contains an interactive video, a practice lesson, and then a timed bonus to beat the clock. Another advantage is that teachers can assign level difficulty (even grade level) to each individual student as students learn at different pace and can master the practice needed to get to their grade level standard. Zearn is not utilized as a grade, it is merely used for mathematical practice, so students feel less pressure to perfect scores.
The disadvantages of not using this program would be not having access to material that supports the learning standard being presented within the classroom. Students who learn by using physical manipulatives might have difficulty understanding the material, versus students who are visual learners. Another disadvantage of using this program might be that students do not see progress in their learning abilities if they are not held accountable to practicing. Students might see themselves lesser than their peers if they realize they are behind in a lesson over their table partner. However, the advantages of using a program for math intervention outweigh the disadvantages as students learn through play.
