Addition, Subtraction and Ten Frames… oh my!

ist2_928159_math_kids

Your child will need to be able to add and subtract fluently.  Students use objects, drawings and written equations to help them solve addition/subtraction problems.  Students will use “ten frames” to help them understand how to “make ten.”  We will also be using kinesthetic activities/centers to practice our math facts.

  • CCSS.Math.Content.K.OA.A.1 Represent addition and subtraction with objects, fingers, mental images, drawings, acting out situations, verbal explanations, expressions, or equations.

  • CCSS.Math.Content.K.OA.A.2 Solve addition and subtraction word problems, and add and subtract within 10, e.g., by using objects or drawings to represent the problem.

  • CCSS.Math.Content.K.OA.A.3 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).

  • CCSS.Math.Content.K.OA.A.4 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.

  • CCSS.Math.Content.K.OA.A.5 Fluently add and subtract within 5.

Article about Ten Frames!

A ten frame is an amazing tool to teach a variety of math skills.

Here is an article from Oregon State University discussing the advantages of using ten frames.

There are some really fun and catchy songs on Youtube to help our kids learn to add and subtract.  Below are some of our favorites.  Please email Mrs. Arsenault if you find any other fun ones on Youtube 🙂  Thanks!

What Makes 10

This is a really fun video and the kids LOVE it!  This video includes equations that “make 10.”  They also include a series of equations with missing addens (4 + __ = 10).  I sometimes pause the video to quiz them.  I also talk to the kids about how a “ten frame” is a great tool for figuring out what that missing adden is quickly.

Doubles Doubles!  I Can Add Doubles!

The song is great for learning those double facts.  (This version uses numbers 1-5.)

There are so many amazing apps for addition and subtraction!  Here are a few that we use in class:

“Freefall Math” by: Merge Mobile

My kids LOVE the “Freefall” apps. This app includes: addition, subtraction, multiplication and division. My students have only played the addition portion of the game so far.  Students are asked to find and drag the equations to the answer  as it falls down or type the answer. I like that adults have a LOT of control in the settings. For example, you can set the game to focus on +1 or only +3.  Price: $0.99

Join smaller numbers together to make bigger numbers. You can adjust the difficulty level.  The addition level is free to try, but you can buy all the levels for $6.99.   My kids really like this app, but I didn’t purchase the additional levels.

Marble Math Jr.

This app is a HUGE favorite.  The kids love it and I love how it really makes the kids use their “mathematical brains!”   It is also a great way to practice listening comprehension skills.  I am not surprised at how many awards this app won over the past year.  Students solve a variety of math problems by collecting numbers as you roll or drag your marble through a series of fun mazes. (with audio questions for emerging readers)  Tip: I set the marble for “drag” because the kids had a hard time tilting the ipad to navigate the maze.

MARBLE MATH JUNIOR CONCEPTS INCLUDE:

• shape recognition/matching
• sequencing number values and ordinals
addition, subtraction and multiplication to 100
• identifying fractions
• counting money
• telling time
• completing addition equations

Bugabaloo Shoes Addition Game

Add up the shoes and click the answer.  Please have your child practice saying the equation and counting the items (or using the “counting on” strategy) before clicking on the answer.
