Developing Strategies for Multiplication and Division Computation
1 iPad Apps
The first app used was Division and it allows students to practice long division while guiding them as they get correct answers and make mistakes.
The second app, Math Bingo allows students to practice double digit multiplication and division through bingo.
The third app, splash math allows students to do double digit multiplication using several different methods.
2 Virtual Manipulatives
In this jeopardy game, students will multiply one and multi-digit numbers. The game is an excellent classroom activity because it has a multi-player feature. http://www.math-play.com/Multiplicaton-Jeopardy/Multiplication-Jeopardy.html
In this manipulative the student has to answer the multiplication questions to make a homerun or to hit the ball. http://www.prongo.com/math/multiplication.html
This manipulate uses a multiplication chart to help students multiply double digit numbers. http://nlvm.usu.edu/en/nav/frames_asid_192_g_2_t_1.html
Key Standards Supported
|4.NBT: Generalize Place Value Understanding For Multi-Digit Whole Numbers.|
|4.NBT.1||Recognize that in a multi-digit whole number, a digit in one place represents ten times what it represents in the place to its right. For example, recognize that 700 ÷ 70 = 10 by applying concepts of place value and division.|
|4.NBT.2||Read and write multi-digit whole numbers using base-ten numerals, number names, and expanded form. Compare two multi-digit numbers based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.|
|4.NBT.3||Use place value understanding to round multi-digit whole numbers to any place.|
|Use Place Value Understanding And Properties Of Operations To Perform Multi-Digit Arithmetic.|
|4.NBT.4||Fluently add and subtract multi-digit whole numbers using the standard algorithm.|
|4.NBT.5||Multiply a whole number of up to four digits by a one-digit whole number, and multiply two two-digit numbers, using strategies based on place value and the properties of operations. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.|
|4.NBT.6||Find whole-number quotients and remainders with up to four-digit dividends and one-digit divisors, using strategies based on place value, the properties of operations, and/or the relationship between multiplication and division. Illustrate and explain the calculation by using equations, rectangular arrays, and/or area models.|
