Description: This Boom Card Activity focuses on practicing the skill of subtracting 10 from multiples of 10 up to 100. Students will see an equation, then translate it into a concrete illustration. This involves drawing an (X) on a "ten," symbolized as a rod or stick, to visually enhance their understanding of subtracting ten from the existing tens. Following this, they will count the total number of the remaining tens. Then students will input the difference by typing the answer into the designated difference box. For learners who may need additional assistance with counting by tens, an "Extra Help" button is available. This resource provides additional support, ensuring every student can grasp the concept successfully. This deck SUPPORTS the following CCSS Math standards. 1.NBT.5: Given a two-digit number, mentally find 10 more or 10 less than the number, without having to count; explain the reasoning used. 1.NBT.6: Add or Subtract multiples of 10 in the range 10-90 from multiples of 10 in the range 10-90 (positive or zero differences), using concrete models or drawings and strategies based on place value, properties of operations, and/or the relationship between addition and subtraction; relate the strategy to a written method and explain the reasoning used.
