Recognising and remembering the different forms that a letter can take increases children’s awareness as they see them in other contexts and begin to use them in their early writing. The simple game play of this visually-engaging app follows the rules of pelmanism. Select a pair of letter pebbles, hear their name and sound and watch to see if they match. If a pair is found, they remain face up. If not, they turn over. Try to remember what you saw though as you might need some of those pebbles later! When a game is over, a new set of pebbles appears with letters selected randomly. Teacher options allow you to choose what matching takes place: lowercase to lowercase, uppercase to uppercase or uppercase to lowercase. FEATURES - Learn the name and sound of each letter and its lowercase/uppercase shape - Turn a pair of pebbles to find matching letters - Use settings to choose matching options: UC-UC, lc-lc or lc-UC - Use settings to reduce/increase the number of pebbles used in a game - A Read Me file with guidance on other ways to support letter recognition in children - No third-party advertising - No in-app purchases.

About

Multi Base Blocks Applications

Features
Read full description

Multi Base Blocks Applications contains four apps to help young children proceed from the concepts of trading and place value through to the written algorithms for addition and subtraction. Preschool children can practice trades and learn about place value and grouping using the applications Win A Block and Trade A Block. School aged children can use the applications Addition and Subtraction to bridge from performing the operations with blocks to carrying out the operations with symbols. On the same screen, students model the problem with multi-base blocks and are guided to perform trades and moves to arrive at the answer. While the students move the blocks, symbols are adjusted to match the student moves through to the final answer. Parents or teachers can help children by making choices concerning grouping size, how many digits or columns in a problem, repeating a problem, creating a specific problem or generating a random problem. The applications are not intended to teach operations in another base, but to help children become familiar with the algorithmic processes so that they can more easily learn addition and subtraction in base 10.
