What Teachers Are Saying

⭐️⭐️⭐️⭐️⭐️"This is all I've ever wanted for mental math. It's got virtually every strategy from basic to more tricky and well thought out lessons, activities and centres. This is by far the best product I've found in 15 years of teaching for teaching students mental math. All in one place, it's everything you need!" Zack A.

⭐️⭐️⭐️⭐️⭐️"This is a gem. Previous feedback is accurate. Extremely teachable resource; well thought out and sequenced, provides multiple ways to learn the concept. This is everything you will need to teach addition and subtraction strategies. I like the files that have differentiated worksheets. I will definitely be using them; as some students in my Gr. 2 room are ready to work on number concepts to 100, while others are struggling with 1-10. Take those "Math Strategies Posters" out of your shopping cart and check out with this, and only this, instead. It's perfect. Stream-lined. accurate." My Dear It's Elementary

⭐️⭐️⭐️⭐️⭐️ "I always get nervous when I spend a lot of money on TpT for something...man, this was TOTALLY worth it. My kids this year really KNOW their facts and I feel like I've accomplished basic facts for the first time in my 11 years of teaching. This is an awesome resource!! I am a dedicated follower! :) LOVE your stuff!" Room Six ROCKS

⭐️⭐️⭐️⭐️⭐️ "Another awesome resource from Shelley Gray!!! I have been using these strategies along with your Grade 2 Math Conversations to review Math concepts with my child, and he is just flourishing this summer. Thank you so much for this!" Joan T.

⭐️⭐️⭐️⭐️⭐️ "Incredible resource!! I was a bit weary of the price, but it truly is worth every penny. This has helped to increase my students' facts more than ever. With a big variety of both regrouping and non-regrouping practice sheets, it made it very easy to scaffold my teaching and lessons to work through these strategies. I liked the variety of worksheets as well. Instead of just simply having them answer questions you have broken these skills down into fun, engaging, and helpful practice. I can't recommend this product enough!" Sarah R.

⭐️⭐️⭐️⭐️⭐️ "Students enjoyed the variety of creative activities and all benefited from the review of mental math strategies. I've looked for something like this for a long time! This resource made addition/subtraction strategies easy to teach. Well worth it." Coffee Girl
