In this movie, you’ll learn how to add and subtract tens and solve sentences that use two-digit numbers. You can skip-count by tens or use a number line or hundred chart. You can hide zeroes to help you add or subtract, or use doubles facts to help you find the sum or difference. Use what you know about adding and subtracting tens to add or subtract 9 or 11. What is 40- 11? Watch the movie to learn different strategies to solve.

#### Math Facts and Number Sense Lesson Plan: The Jelly Bean Game

In this lesson plan which is adaptable for grades K-4, students will use jelly beans in an online game and real jellybeans as math manipulatives to practice number sense concepts, such as counting, more and less, estimation, algebraic thinking and missing addend equations, and addition and subtraction math facts. This lesson plan is aligned to Common Core State Standards.  See more »

I love the quick description of each activity listed above. It’s just enough to know if it fits what you want your students to accomplish. I really like the idea in the Jelly Bean game of having students recreate the game they just played (or an alternative) using jelly beans/manipulatives. That is a great way for students to continue using the concepts they just learned in the game. Since my classroom isn’t 1-1 I could have some students on the game and some doing this activity. They are all working on the same skill but using different approaches! While I’m sad I never knew about these resources until this workshop, I’m so glad I can begin to utilize them now!

I love this! Great collection of resources both digital and traditional–from hands on manipulatives (base ten blocks, candy, flipcharts, etc.), to games (Jelly bean game, etc.), to further reteach and extension ideas for at home and school. I like that teachers and/or parents can use this as a well rounded plan for a unit or skill with multiple levels of students. It really lays out lessons for you which can be hard to come by when you’re a teacher. This is literally like a one stop shop! You don’t need to have 1-1 to utilize these lesson ideas–these activities could be done in centers as well (which is what I prefer as a teaching strategy for math anyway). I wish I had known about this earlier in my teaching career!

I liked in this collection, the Adding and Subtracting Tens Background Information for Teachers and Parents. This would be a great resource for parent to help their kids who are struggling at home. Giving them ideas and games to practice outside of school will help them gain confidence and become more fluent in the desired area.

This collection of resources is a great place to begin! I would use the number sense video to introduce and then move forward with my lesson. After the mini lesson, I would use the game and activities for 2 of the independent activities during my small group math lesson.
