It's time to practice basic addition and subtraction facts within ten! This first grade-level lesson will help your students become more confident and accurate in their basic addition and subtraction skills. All addition and subtraction facts in this online math lesson feature addends, minuends, and subtrahends within ten.
In this drill-style lesson, math problems are presented in a horizontal format. Students will fill in the blank with the correct answer. If students need a little extra help, they can click on the hint button, which will show them a picture of dice to help them visualize the math problem. They can also click the speaker icon in the upper-left corner of their practice screen to have the question read aloud to them in a clear voice. (This is a great option for ESL/ELL students, or students who prefer auditory learning.) If students answer a question incorrectly, a detailed explanation page will appear with a similar visual representation as the hint, showing them how the addition or subtraction problem should be solved. This way, students can learn from their mistakes and improve their skills throughout their practice session.

Operations And Algebraic Thinking
Add And Subtract Within 20.
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 - 4 = 13 - 3 - 1 = 10 - 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 - 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
