In this smartboard lesson the numbers 11-20 are reviewed in various ways. Each number has 3 slides to go with it. On the first slide of each number there is an opportunity for students to count objects and tell how many there are. On this page students can then click a star that will reveal the answer. On the second page of each number there is an opportunity to write the number and represent the number with pictures that can be drug across the smartboard. On the third page of each number there is a page on that number from a number book I created. In this book students can represent each number in six different ways (writing the number, writing the word, making a ten frame, tallying, drawing base ten blocks, and drawing a picture). After going through each number there is a link to an interactive game that can be played. There are also links to two different songs with the numbers. Finally, there is a game attached that can be printed and played with your students. This is a great 11-20 number review for any early childhood classroom. This is the second number review lesson, I also have a 1-10 review lesson in my TPT store.
