Apps
Number Line App-Number Line helps students visualize number sequences and model strategies for addition, subtraction, multiplication, and division. It can be used to represent sequences of numbers, including whole numbers and multiples of a variety of numbers. Available as an app for the iPad or as an online web app.
Books
The link below will direct you to books that can be purchased at amazon. These were added with the intention of providing a list of appropriate books that they could check out from our local library. This link was chosen because you can preview the books and see what the cover looks like so it will be easier to find at the library.
Young Mathematicians at Work: Constructing Multiplication & Division Catherine Fosnot and Maarten Dolk explore how 3rd-5th grade students construct knowledge of multiplication and division. Chapter 6 discusses how the array model relates to algorithms.
Multiplication and Division Books Visit the Math Learning Center Virtual Bookshelf for titles on multiplication and division.
Learning to Thinking Mathematically With the Ratio Table Blog entry introduces Jeffrey Frykholm's book, Learning to Think Mathematically With the Ratio Table, which inspires educators to consider ways to use ratio tables to promote student understanding.

Games For Kids
Camel Times Tables Determine the total number of pieces of fruit on a tray holding plates that each have the same number of pieces of fruit.
Connect the Dots: Multiples In these connect the dot pictures, players set the counting sequence. Set the pictures to practice counting by 1s, 5s, 10s, or set your own number to practice multiples.
Ghost Blasters Blast every ghost that displays a multiple of the number you choose. Game may be set for multiples of any number from 2-20.
Math Madness Fill in the addend, subtrahend or factor to score points in this basketball arcade game.
Meteor Multiplication As meteors with multiplication problems approach a star station showing a given product, fire them down by clicking on the expression that goes with the product.
Multiplication Grand Prix Race against the computer or other students by clicking on the correct product in a series of multiplication problems. Also try a similar game, Tractor Multiplication.
Sum Sense Multiplication Drag and drop number cards--with unknowns in all positions--to make a multiplication equation.
Bugs in the System Click and drag bugs, putting them into the correct color position on a bar graph to count totals.
Cyber Olympics Analyze data and click on contestants with the fastest practice times to compete in each event. Cyberchase game.
Handling Data Game Several different kinds of data are represented in a variety of activities. Players must use bar charts, interpret information, observe & record. Timer is optional.
lMr. Nussbaum's Graph Master Students create a bar graph, line graph, and pie chart based on data collected from classmates. The program then asks them eight multiple choice questions based on the data entered.
