This PowerPoint includes 46 slides and 4 activities for students to complete as a group or individually on a computer or iPad. Students will practice counting objects (eyes, ears, shoes, parts of a mustache and twins) by twos to 20. They will practice finding the multiples of two within numbers 1-20 and finding the missing number when counting by twos to 20. Finally, students will practice their missing number fluency by quickly identifying what number is missing in a group of three. This is a great way to introduce skip counting, even numbers or multiplication as repeated addition.
