This bundle is great for teachers to use when teaching students how to round to the nearest 10 and 100 through the use of music. Sometimes music is a great way to teach students hard concepts in math. With two easy tunes that ANY teacher can sing-Twinkle Twinkle Little Star and If You're Happy and You Know it, students can use these songs to remember how to round to the nearest 10 and 100. Perfect also for Early Intervention teachers and Special Education teachers. Can also be used as a review
