Happy ticket. Oral account treasury quest. Addition and subtraction within 100. Astakhova N.

"Oral account is gymnastics for the mind." The “Happy Ticket” simulator, designed for students of grades 1-2, will help to make it interesting and diverse. The task of each turn is aimed at working out a certain type of examples of an oral account: an account within 10, with a transition through a dozen within 20 and 100. The simulator is suitable for both individual work and collective quests in lessons and mathematical circles. The simulator has a meta -subject approach: the guys should not only solve an example, but also find a country on the map of the world. It is recommended for use along with the book “Quest Trinager Oral Account. Addition and subtraction ”, as well as notebooks for collective quests.
