This product is HALF OFF FOR THE FIRST 48 HOURS! Introducing the "Using Tens" strategies for equations through 20! In my 22 years of teaching, I’ve learned to promote success through scaffolding instruction, differentiating to meet students’ needs, and giving children multiple opportunities to learn a skill. With all this in mind, I have included flash cards, 5 types of strategy cards (including basic and advanced levels), number lines, manipulatives, 5 simple games, one no-prep center, and two chants, all thoughtfully scaffolded into the following sections:
You may also be interested in my giant BUNDLE of 38 first grade songs and videos, available HERE. This set teaches ALL Common Core 1st grade standards. Songs that directly relate to this packet are: "Know Those Tens," "Using Tens," "Add 3 Objects," "Adding 3 Numbers," "Equals Means 'The Same As',"and "Mystery Numbers." (The lyrics to the first two songs are included in this packet.)
Finally, these are the related Common Core and TEKS standards:
Apply properties of operations as strategies to add and subtract. Examples: ... To add 2 + 6 + 4, the second two numbers can be added to make a ten, so 2 + 6 + 4 = 2 + 10 = 12. (Associative property of addition.)
Add and subtract within 20, demonstrating fluency for addition and subtraction within 10. Use strategies such as ... making ten (e.g., 8 + 6 = 8 + 2 + 4 = 10 + 4 = 14); ...
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. By end of Grade 2, know from memory all sums of two one-digit numbers.
