First grade math

On this page you can see a list of all the skills that children will learn in Mondiso Math - first grade. When students enter Mondiso for the first time they enter the “First Year Bay” – a treasure map with 10 overall missions to solve. Each mission consist of several math exercises and games which are organized into categories. You can mouse over each skill to view more information

Mission 1 Numbers and Counting

1.1 Meet the Numbers

Description

The numbers enter, and present themselves one by one (1-9 and then 0), then they jump to their place in the number sequence.


Objective

Familiarization with the numbers 0-9 including their names and properties, in addition to their place in the number sequence.


1.2 Put Numbers on the Objects

Subject
