Education technology company MasteryConnect is buying Socrative for $5 million.

Socrative, headquartered in Cambridge, Massachusetts, develops mobile and desktop applications for educational exercises, games and other tools that allow students to give teachers feedback. The goal is for teachers to be able to personalize instruction. 

Salt Lake City, Utah-based MasteryConnect provides learning tools for children in kindergarten through grade 12. The company's application allows teachers to track student learning. The acquisition builds MasteryConnect's reach to more than 21 million students and 1 million teachers. Right now, the company's services are used in 85 percent of U.S. school districts, it says, and in more than 175 countries.

Teaching tools have been a popular M&A target lately. In May, Falfurrias Capital Partners bought a majority stake in American Safety Council Inc., an e-learning business that provides workplace safety training. Before that, in April, John Wiley & Sons (NYSE: JWa, JWb) agreed to buy CrossKnowledge, a digital learning service, for $175 million.
