*This product includes three sets of task cards for adding and subtracting decimals using strip/tape diagrams, each set contains 24 cards, for a total of 72!
*There are also two recording sheets, one if you want students to record only the answer and another if you want students to also record the equation they used to find the answer.
*Product addresses NEW math TEKS for 4th grade!
*Each task card includes a QR code for students to check their work. A version without QR codes is also included.
*While problems primarily focus on combining parts to make a whole, students will have to subtract decimals to find missing parts in problems.
*Cards are differentiated to address a variety of learning needs.
-----Set 1 provides a diagram where students are finding either the sum or the missing part with no more than two parts. This set works well with an intervention group or when students are just beginning.
-----Set 2 provides a diagram and has students find either the sum or missing part with three parts.
-----Set 3 includes word problems for students to find the sum or missing part and identify which diagram best represents the word problem. Great prep for STAAR and other state tests!
*Tape diagrams go by many names and you may hear them called strip diagrams, bar diagrams, or stick diagrams. Sometimes they are called part-part-whole boxes. Tape diagrams can help students visualize relationships between parts and wholes and can be useful in solving many types of word problems. They are great with helping students build algebraic reasoning skills because they bump the rigor! Students aren’t following a defined equation, but are developing their own equations to solve for X.
*This set is designed primarily for 4th and 5th grade students learning to add and subtract decimals to the hundredths place.
SUGGESTIONS FOR USING THIS PRODUCT
*Print on card stock and use a zip tie to bind together for durability. Laminating is a plus!
*Place in math centers or stations for partner practice.
*Use with a small group for intervention or enrichment.
*Place cards around the room and have students rotate to solve problems. This can also be done at desks by playing ‘scoot.’
*Task cards work great for early finishers!
*Place a task card on the projector as a warm up during math or morning work. You can also give students a copy and have them add the card to their math notebooks and solve the problems.
*Place task cards with a board game so that students solve problems before advancing spaces on the game board.
*There are many ways to use task cards in the classroom. Google ‘task cards’ for more ideas!

TEKS (new math TEKS beginning 2014)
*4.4A-- Add and subtract whole numbers and decimals to the hundredths place using the standard algorithm.
*4.5A--Represent multi-step problems involving the four operations with whole numbers using strip diagrams and equations with a letter standing for the unknown quantity.
*5.NBT.B.7--Add, subtract, multiply, and divide decimals to hundredths, 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.
*Build algebraic thinking skills with these Pre-Algebra Task Cards!
*Worksheets for adding and subtracting decimals with tape/strip diagrams can be found HERE!
As a Texas teacher, the products I make are designed around the standards for the state of Texas, known as the Texas Essential Knowledge and Skills (TEKS) and are carefully crafted to help students be successful on the Texas STAAR test. I use the challenge of the TEKS and released STAAR assessments as models to guide me when putting together lessons and materials for my students. Thus, I am careful to post products that, in my judgment, align with these standards. I am not affiliated in any way with these entities and any and all claims of alignment are my claims, not those of the groups behind the TEKS or STAAR test. Please contact me if you have questions.
There are many teachers in Common Core states looking for quality materials. If one of my TEKS based products addresses a skill in the Common Core, I will include those standards in this description. I do not teach the Common Core in my classroom, but am familiar with the standards. I am not affiliated with the entity behind Common Core and all claims of alignment are my judgment, not those of the groups behind the Common Core.
