In this interactive math lesson, children will practice multiplying 2-digit numbers by multiples of ten. Math problems are presented in a variety of formats in this fourth grade math activity, including vertical multiplication problems, horizontal multiplication problems, and multiplication word problems. After going through this online math game, students will gain a greater understanding of basic multiplication skills.

Here are a few examples of math problems students may encounter in this lesson: "51 x 60 =", "Multiply 46 and 30," and "Luca was baking cookies at Victoria's bakery. Each tray holds 12 cookies. Luca baked 70 trays of cookies. How many cookies did he bake?"

If students have trouble answering a math problem, they can click on the "Hint" button for a little extra help. They will be shown a relevant clue; in this case, the first step in solving the multiplication problem. If students answer a math problem incorrectly, a detailed explanation page will pop up, showing them how to solve the problem step by step, so they can learn from their mistakes along the way.

In addition to optional hints and detailed explanations, every “I Know It” lesson offers several features to help children make the most out of their math practice time. A progress-tracker shows students how many questions they have answered in the lesson so far. A score-tracker shows them how many questions they have answered correctly. Plus, a speaker icon indicates the read-aloud feature; students can click it and the question will be read out loud to them in a clear voice. (What a great option for ESL/ELL students!)
