In this math movie, you’ll learn different ways to make ten, such as 1 + 9 = 10 and 7 + 3 = 10, and how to break ten apart. You'll learn how you can use combinations of numbers that add up to ten to help you add and subtract more easily. You'll also find out how you can use fact families and related facts to help you add and subtract. You'll even learn how to solve missing number problems more easily! Find out how you can use number triangles to help you solve tricky number sentences!
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 »
In this lesson plan which is adaptable for grades 1-5, students will use an online math game to practice creating number combinations (such as whole numbers which add up to 10, or decimals which add up to 1.) Students then create their own version of the game using hands-on materials. This lesson plan is aligned to Common Core State Standards. See more »
In this multi-day lesson plan for grade K through 3, students use a BrainPOP Jr. movie, graphic organizer, and flip chart to deepen their understanding of basic addition and mathematical thinking skills. This lesson plan is aligned to Common Core State Standards. See more »
This page contains information to support educators and families in teaching K-3 students about ways to make ten and combinations of 10. The information is designed to complement the BrainPOP Jr. movie Making Ten. It explains the type of content covered in the movie, provides ideas for how teachers and parents can develop related understandings, and suggests how other BrainPOP Jr. resources can be used to scaffold and extend student learning.

These activities are designed to complement the BrainPOP Jr. Making Ten topic page, which includes a movie, quizzes, online games, printable activities, and more. See more »
Decompose numbers less than or equal to 10 into pairs in more than one way, e.g., by using objects or drawings, and record each decomposition by a drawing or equation (e.g., 5 = 2 + 3 and 5 = 4 + 1).
For any number from 1 to 9, find the number that makes 10 when added to the given number, e.g., by using objects or drawings, and record the answer with a drawing or equation.
Relate counting to addition and subtraction (e.g., by counting on 2 to add 2).
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as counting on; making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); decomposing a number leading to a ten (e.g., 13 – 4 = 13 – 3 – 1 = 10 – 1 = 9); using the relationship between addition and subtraction (e.g., knowing that 8 + 4 = 12, one knows 12 – 8 = 4); and creating equivalent but easier or known sums (e.g., adding 6 + 7 by creating the known equivalent 6 + 6 + 1 = 12 + 1 = 13).
Understand the meaning of the equal sign, and determine if equations involving addition and subtraction are true or false. For example, which of the following equations are true and which are false? 6 = 6, 7 = 8 – 1, 5 + 2 = 2 + 5, 4 + 1 = 5 + 2.
Determine the unknown whole number in an addition or subtraction equation relating three whole numbers. For example, determine the unknown number that makes the equation true in each of the equations 8 + ? = 11, 5 = _ – 3, 6 + 6 = _.
Fluently add and subtract within 20 using mental strategies.2 By end of Grade 2, know from memory all sums of two one-digit numbers.
