Students will practice basic subtraction facts in this interactive math lesson geared toward kindergarten. In this drill-style math activity, students will master subtraction math facts within five. Upon completion of this math practice activity, children will become more confident and proficient in basic subtraction facts.

Questions in this online math game are presented in a straight-forward drill format. Students will recall basic subtraction facts, such as 4 - 0, 4 - 4, and 0 - 0. Students can click the "Hint" button if they need a little extra help recalling a subtraction fact. The hint consists of an illustration, such as a specific number of counters with several counters crossed out to represent "taking away from" the whole. When students complete a math fact incorrectly, they will be shown a detailed explanation page to help them learn the correct response. In this way, students move through the math lesson having learned from past mistakes.

Several helpful tools built into each of the math lessons on "I Know It" help students make the most of their math practice session. For example, a progress-tracker shows students how many questions they have answered so far out of the total number of questions in the practice activity. A score-tracker lets them see how many questions they have answered correctly so far. Plus, students can click the speaker icon to have the question read aloud to them in a clear voice. This is an excellent resource for ESL/ELL students and students who are auditory processors.
