This is an AMAZING resource! I was feeling anxious about teaching the various subtraction strategies - now I am not. Thank you for all of your hard work!

My only complaint - I wish I had bought the mega pack with the addition units too! I've added it to my wish list for next time :)

I think the Mental Math Strategy unit for Subtraction is awesome!! My goal this year is really is for my students to fluently be able to add and subtract. This unit provides so many opportunities to all the students to do this. The lessons, activity sheets and follow up center activities are great. I really love the recording sheet for the center activity to make them accountable for their work. Also, the links to the youtube videos are great!

Product Questions & Answers

n/a
On  December 6, 2012,  Buyer asked:
Hi Shelley, Here's my situation...after several days of looking through many of the mental math strategies out there, I was happy to find your to be so thorough. Even though I've already covered Doubles and Doubles+1 with my students, I thought that yours would be perfect for review and a great resource for next year. Here is my problem...after looking at the wide variety of units you have available, I decided on your Mental Math Strategy Units: the Complete Addition Collection, I accidentally purchased the Subtraction Collection by mistake...call it a busy day and late night brain stutter...I cannot afford to purchase both. Is there something that I can do? I do not need the subtraction unit, we are currently covering the addition strategies. Can I exchange it? Is there something I can do? Thank you for understanding, Shelley!
Teachers Pay Teachers
On  December 7, 2012Shelley Gray answered:
Hi there! These types of situations are tough since the files are digital and can't really be exchanged; however I am willing to work with you to find a solution that works. I am actually on vacation right now and only have my phone with me, but could you email me at shelley_gray_@hotmail.com and I will email you when I get home on Monday?

Thanks so much,
Shelley

Do you have a version of this where it just is the make a 10 strategy? I love all the components, but that one part would supplement my curriculum perfectly!

On  November 26, 2012Shelley Gray answered:
Hi there. I sure do! If you copy and paste the link below into your browser, it will take you to the Mental Math section of my store. I have a Making 10 unit for addition, as well as a Using Ten unit for subtraction. Feel free to ask if you have any other questions.

Hi,
Are games included in your mental math addition/subtraction units?
If so, can you tell me the names/concepts of them?
Thanks so much,
Ali
Teachers Pay Teachers
On  August 16, 2012Shelley Gray answered:
Hi Ali! I am so sorry that I did not get back to you sooner! I was on vacation, and lost all cell signal and could not find a wireless connection anywhere. It was driving me crazy (ask my husband :) )

Anyways, all of the mental math units include center activities and hands-on activities that can be played as games if you wish. For each unit, the activities all center around the specific concept. For example, in the "Doubles" unit, you will find activity sheets, center activities and hands-on activities that all center around the common theme of "Doubles." All of the resources that you need in order to teach the concept is included. It may help you to look at the feedback that has been submitted by other buyers. You can find this on the "feedback" tab on the product page. If you have any other questions, feel free to ask.

Also, I see that you asked this question on the day of the Back to School sale. If you decide to purchase either of these resources, I would be happy to honor the BTS pricing, which means you would receive $7 off of the Mental Math Subtraction Collection and the Mental Math Addition Collection. If you would like to, you can contact me at shelley_gray_@hotmail.com and we can make arrangements for this.

Thanks, and again, I am VERY sorry about not getting back to you sooner.

Have a great day,

Shelley
