Hands vs Subtraction with regrouping

Hands-On Math Line Design is an interactive learning environment where students explore and discover the fundamental ideas of geometry. It is a perfect classroom tool for mathematics enrichment. While using this app students will use mathematical thinking skills to create colorful designs. Students will be amazed that curved designs can be created with only straight line segments. Encourage your students to take some time to explore LineDesign, and as they do help them to discuss their findings. Elicit math vocabulary while creating designs. Younger learners will benefit from using the terms such as line, line segment, end point, intersection, rectangle, square, circle, and triangle. For older students teachers may want to use some of the options available by tapping the grid icon. Based on the shape selected either a rectangular or polar coordinate graphic system is displayed. Teachers will want to use these features as components of their coordinate geometry and angle measurement curriculum. Topics: Properties of Geometric Shapes Geometric Terminology Classification of Angles Properties of Polygons Coordinate Systems (Rectangular and Polar) Angles and Degrees Parts of a Circle Mathematical Thinking and Reasoning Relationship between Geometry and Art

Subtraction with Eggs app provide the simplest way to learn subtraction by regrouping,it can help kids to know how to borrow in subtraction , this app use hatch out birds to help kids understand subtraction and this app dynamic to generate subtraction's questions, so you can get a lot of practice questions. There are 3 functions in this app: Function 1-> Subtract one-digit numbers - up to 10 Function 2->Subtract two-digit numbers - with regrouping Function 3->Subtraction practices game (Play it,tilt to move left or right.) The function 2 can help kids learn subtraction with regrouping more easy. For example: 82-27 =? you can follow the steps to do subtraction by regrouping: 1. 2 is less than 7, so we need to regroup 1 ten as 10 ones, drag 1 ten to ones’ box. 2. After regroup, there are 7 tens and 12 ones. 3. Click 7 eggs to hatch out 7 birds 4. Click 2 tens eggs to hatch out 20 birds 5. Check the remaining number of eggs, click the right answer's button It has 3 levels in the function 2,you can click the star button to switch levels: 1 star level : subtraction that don't need regrouping 2 stars level: 2 digits minus 1 digit and need regrouping 3 stars level: 2 digits minus 2 digits and need regrouping If you are interested in this app, you can watch the following video: https://www.youtube.com/watch?v=2MVMSE1kIyk As a MOMs with Apps member,we follow the "Know What's inside" best practices for kids' apps. http://momswithapps.com/
