The virtual manipulative that I ended up exploring was base blocks. The main goal of this virtual manipulative was to show students a number and have them express it through the base blocks.

Another reason that it works better

ACIDS & BASES Acids/Bases Basics Acids and bases are common solutions that exist everywhere. Almost every liquid that we encounter in our daily lives consists of acidic and basic properties‚ with the exception of water. They have completely different properties and are able to neutralize to form H2O‚ which will be discussed later in a subsection. The table below compares the different properties between them: pH Scale Since acids increase the amount of H+ ions present and bases increase
