Price: 95 points or $0.95 USD
Subjects: math
Grades: 2,3,4
Description: Perfect for summer review or test prep! Students will practice two-digit subtraction across zeroes (subtracting from tens) in this fun, summer themed activity. Students will see a two-digit minus one-digit or two-digit math sentence in the standard algorithm vertical form. They will fill in each box one at a time to form a two-digit or one-digit difference. Students will SHOW ALL OF THEIR WORK DIRECTLY ON THE SLIDE (including the regrouping/ borrowing)!!! If a student makes a mistake, they will receive immediate feedback of where the mistake(s) are, so they can make corrections and resubmit. 2.NBT.7 CCSS.MATH.CONTENT.2.NBT.B.7 Add and subtract within 1000, 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. Understand that in adding or subtracting three-digit numbers, one adds or subtracts hundreds and hundreds, tens and tens, ones and ones; and sometimes it is necessary to compose or decompose tens or hundreds. 3.NBT.2 CCSS.MATH.CONTENT.3.NBT.A.2 Fluently add and subtract within 1000 using strategies and algorithms based on place value, properties of operations, and/or the relationship between addition and subtraction. 4.NBT.4 CCSS.MATH.CONTENT.4.NBT.B.4 Fluently add and subtract multi-digit whole numbers using the standard algorithm.
