## Interactive Math Lesson - Number Bonds Featuring Addition and Subtraction within Ten

Number bonds are an excellent way for young children to visualize basic addition and subtraction facts! Use this interactive math activity to help your first-grade students practice adding and subtracting within ten. Children will use number bonds to solve basic math facts involving addition and subtraction within ten. Your class will love this fun, engaging math activity from iKnowit.com!

What kind of questions does this first-grade math game feature? You can be sure your students will be challenged and engaged by a variety of number bond math problems! Many questions require little ones to "Fill in the missing number" for the number bond. Some problems are presented in multiple-choice format while others require students to fill in the blank. Students will use the number bonds to solve a variety of math facts: 6 + 4, 7 + 2, 6 + 0, 9 – 5, and 6 – 3, for example. If students need a little extra help solving one of the math problems, they can click on the "Hint" button. The hint provides a helpful illustration, such as a ten-frame, to help children visualize the math fact in a different way. Children gain new understanding without having the answer given away by the hint. When students answer a question incorrectly, a detailed explanation page appears on their screen, providing an easy-to-understand explanation to help them learn from mistakes.

Every math lesson in the I Know It program features several built-in tools that help students make the most of their math practice sessions. For example, a progress-tracker in the upper-right corner of the practice screen shows children how many questions they have answered out of the total number of questions in the math lesson. A score-tracker beneath that lets students see how many points they have earned for correct answers. The speaker icon in the upper-left corner of the practice screen indicates the read-aloud feature. Students can click this button to have the question read out loud to them in a clear voice. This is a great resource for ESL/ELL students and children who excel with auditory learning! Each one of these lesson features is designed with your students' success in mind.
