1학년: 미니 수학 미스터리

Does your learner like to solve fun mysteries? Well, let them put on their detective hat and get to work using their 1st grade math skills! Mini Math Mysteries are a fun 'game-like' activity to practice 1st grade math skills. They follow a simple elimination structure where learners will be using the answers to the math questions to eliminate possibilities. This is an ongoing class, so you are free to join in and leave as you please. 

At the beginning of each class, learners will hear a short story to preface the mystery they will be solving for the day. Then, it is time for our math detectives to get to work! Learners will answer a variety of questions based on 1st grade content to solve the mystery. They will fist solve the math questions, and then they will look for their answers in the boxes and eliminate the boxes with a matching answer on our shared screen. After answering all questions, only one image will remain (that image will contain a number that didn't match any of the answers to the questions) and that box is the solution to our mystery! 

Some of the math concepts we will be working on include:

-Comparing Numbers
-Missing Numbers in Addition and Subtraction Sentences
-Number Words
-Reading Bar Graphs
-Addition and Subtraction within 20
-Addition within 20 (Questions and Word Problems)
