When your second grade students practice addition and subtraction skills in this online math game, they will have access to some awesome built-in math lesson features designed to help them make the most of their math practice session. For example, children can click on the "Hint" button to view a custom clue for the math problem. The hint consists of a written or pictorial clue that points students in the right direction without giving away the answer. When students answer a question incorrectly, a detailed explanation page will show them the correct answer, accompanied by an easy-to-understand explanation. This way, students can learn from prior mistakes as they progress through the interactive math activity.

In addition, this second grade mixed addition and subtraction activity comes with other handy features that enhance the math practice experience for kids. A progress-tracker in the upper-right corner of the practice screen shows students how many questions they have answered out of the total number of questions in the math lesson. A score-tracker beneath that lets students know how many points they have earned for correct answers so far. Opposite, a speaker icon indicates the read-aloud feature; students can click the button to have the question read out loud to them in a clear voice. This resource is ideal for ESL/ELL students and children who excel as auditory learners. Each of the I Know It lesson features is designed with your students' math achievement in mind.
