Khan Academy
How Can Teachers Use It? Khan Academy's 5th Grade Math content puts Common Core-aligned lessons at your students' fingertips. The lessons here are divided into six tutorials: Arithmetic Operations, Fractions, Place Value and Decimals, Measurement and Data, Geometry, and Algebraic Thinking. Every tutorial includes videos and practice exercises.
Website at Code.org
What's It Like? Code.org's tutorial was created to pique kids' interest in programming in just one hour. As part of the "Hour of Code" initiative, the site -- among others -- aims to get millions of students to try out programming, if only for one hour.
Codecademy
What's It Like? In Codecademy, older kids and teens write computer code. They set their own pace through lessons on every major modern programming language, including PHP, Javascript, Python, Ruby, HTML, and CSS. First, they create an account using an email address or an existing Facebook, Twitter, or Google account.
Scratch
Jumpstart future programmers with adaptive sandbox tool
Easy Studio - Animate with Shapes!
What's It Like? Easy Studio - Animate with Shapes! is a success-oriented app that empowers kids to try their hand at basic animation. Based entirely on creating moving scenes with colorful shapes, this amazing app includes a fun tutorial in Easy Mode that's simple enough for even young kids; they can fill in images of animated geometric shapes, a train, and an airplane to create simple animated scenes in just a few minutes.
Number Frames, by the Math Learning Center
Number Frames help students structure numbers to five, ten, twenty, and one hundred. Students use the frames to count, represent, compare, and compute with numbers in a particular range.

The frames help students see quantities as equal groups of other quantities and in relation to benchmark quantities. This helps primary students move away from one-by-one counting toward more efficient ways of counting and computing. As students advance, custom frames can be constructed to help visualize factors, products, fractional parts and more.

These virtual versions of number frames are open-ended educational tools, ideal for elementary classrooms and other learning environments that use iPads.
Number frames are a key model used in Bridges in Mathematics, second edition. Online preview available at: www.mathlearningcenter.org/bridges
Number Line, by the Math Learning Center
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.

Students can use what they know about number relationships and computation to identify missing elements of sequences shown on the number line.

This virtual number line is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPads.

For more Number Line resources and other apps, visit:

www.mathlearningcenter.org/apps

FEATURES:

• Mark the number line with multiples of any whole number from 1 to 100.

• Add and manipulate forward and backward jumps.

• Hide and reveal numbers on the number line.

• Use the drawing tools to annotate work and show understanding.

• Write equations and expressions with the text tool.
Geoboard, by The Math Learning Center
Geoboard is a tool for exploring a variety of mathematical topics introduced in the elementary and middle grades. Learners stretch bands around the pegs to form line segments and polygons and make discoveries about perimeter, area, angles, congruence, fractions, and more.
This virtual version of the manipulative is an open-ended educational tool, ideal for elementary classrooms and other learning environments that use iPod Touches, iPhones, or iPads.

FEATURES
• Create line segments and polygons by stretching bands around the Geoboard’s pegs.
• Choose from 5 different band colors; 8 band colors on the iPad.
• Fill individual shapes with a transparent color, or use the Fill All button to toggle all the bands between filled and unfilled.
Counting Board
This is a colorful teaching tool for your kids to learn the basic of numbers. It suitable for age from 2 to 4.

Features:
1. Teach your children to count from 1 to 100 by tapping
the numbers one by one and read it loudly.

2. Learn add method:
e.g. Learn 5 + 2 = 7. First tap 5, and then tap next 2 blocks, count the blocks from 1 to 2 while tapping.
The answer will be 7.

3. Learn minus method:
e.g. 16 - 4 = 5, First tap 16, and then tap previous 4
blocks, count the blocks from 1 to 4 while taping,
The answer will be 11

4. Let your kids to use their imagination to draw a picture.
Reflex: Math Fact Fluency
What's It Like? Reflex: Math Fact Fluency teaches math facts for addition and subtraction for numbers 0-10, and multiplication and division for numbers 0-12. It's best for students who already understand basic math operations and need practice to improve speed and accuracy. A character named Crabby walks kids through the setup.
Number Pieces Basic, by the Math Learning Center

Number Pieces Basic helps students develop a deeper understanding of place value while building their computation skills with multi-digit numbers. Students can use the number pieces to represent multi-digit numbers, count, regroup, add, and subtract. The drawing tools allow students to label representations and show their understanding.

Note: Number Pieces, an advanced version of Number Pieces Basic, is also available in the App Store. Number Pieces has additional features for representing larger numbers and multiplication and division concepts.

FEATURES

• Add and manipulate pieces (ones, tens, and hundreds).

• Join pieces in groups of ten or break them apart (e.g., 10 ones into 1 ten and vice versa).

• Choose from three different colors to clearly identify groups or pieces.

• Move, rotate, and duplicate pieces individually or as a group.

• Use the drawing tools to label representations and show understanding.

• Write equations and expressions with the text tool.
