What educators are saying
I love this resource! Some students struggle with number line addition but this worked perfectly especially with the language used on the sheet.
My students have fully embraced the vocabulary of stepping, hopping, and jumping to explain their moves on an open number line! This has been incredibly helpful to help them with their number sense operations and how they interact with addition!
Description
"Jump! Hop! Step!" Open number line strategy for adding three-digit numbers. Supports Common Core standards 2.NBT.5 and 3.NBT.2, addition within 1000 based on place value strategies.
***Check out the PREVIEW and thumbnails for a detailed view of the strategy!***
This strategy requires students to first draw an open number line beginning in the first number of the equation, then expand the second number into hundreds, tens, and ones to determine the number of jumps (hundreds), hops (tens) and steps (ones) up the number line to go. Students then make the moves and arrive at the correct answer. This strategy highlights place value & number sense knowledge as a strategy for solving 3-digit addition. Use this strategy as a step to understanding the "math" behind the standard algorithm for three digit addition.
Packet contents include:
Strategy Posters: Illustrates the 3 steps in the Jump! Hop! Step! strategy: Color and B&W versions.
Strategy Slips: Smaller versions of the strategy posters. Perfect for attaching to homework, sending home to parents, or for gluing in interactive math notebooks or learning journals.
8 Practice Sheets: Scaffolded, guided practice with the Jump! Hop! Step! strategy. Practice pages are perfect for morning work, centers, homework, assessment, or intervention practice for students still struggling with 3-digit addition.

CCSS2.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.
