Add and subtract two- and three-digit numbers using place value to partition, rearrange and regroup numbers to assist in calculations without a calculator <ul> <li>using partitioning and part-part-whole models and the inverse relationship between addition and subtraction to solve addition or subtraction problems, making informal written ‘jottings’ to keep track of the numbers if necessary</li> <li>using physical or virtual grouped materials or diagrams to make proportional models of numbers to assist in calculations, for example, to calculate 214 + 325, representing 214 as 2 groups of 100, one group of 10 and 4 ones and 325 as 3 groups of 100, 2 groups of 10 and 5 ones, resulting in 5 groups of 100, 3 groups of 10 and 9 ones, which is 539</li> <li>choosing between standard and non-standard place value partitions to assist with calculations, for example, to solve 485 + 365, thinking of 365 as 350 + 15, then adding the parts, 485 + 15 = 500, 500 + 350 = 850</li> <li>solving subtraction problems efficiently by adding or subtracting a constant amount to both numbers to create an easier calculation; for example, 534 − 395, adding 5 to both numbers to make 539 − 400 = 139</li> <li>justifying choices about partitioning and regrouping numbers in terms of their usefulness for particular calculations when solving problems</li> <li>applying knowledge of place value to assist in calculations when solving problems involving larger numbers; for example, calculating the total crowd numbers for an agricultural show that lasts a week</li> </ul>
VC2M3A01

Recognise and explain the connection between addition and subtraction as inverse operations, apply to partition numbers and find unknown values in number sentences <ul> <li>partitioning numbers using materials, part-part-whole diagrams or bar models, and recording addition and subtraction facts for each representation, explaining how each fact is connected to the materials, diagrams or models (for example, 16 + 8 = 24, 24 − 8 = 16, 8 = 24 − 16)</li> <li>using the inverse relationship between addition and subtraction to find unknown values with a calculator or by counting on; for example, representing the problem ‘Peter had some money and then spent $375. Now he has $158 left. How much did Peter have to start with?’ as □ − $375 = $158 and solving the problem using $375 + $158 = $533; or solving 27 + □ = 63 using subtraction, □ = 63 – 27, or by counting on 27, 37, 47, 57, 60, 63, so add 3 tens and 6 ones, so □ = 36</li> <li>exploring Aboriginal and/or Torres Strait Islander Peoples’ stories and dances that show the connection between addition and subtraction, representing this as a number sentence and discussing how this conveys important information about balance in processes on Country/Place</li> </ul>
VC2M3A02

Extend and apply knowledge of addition and subtraction facts to 20 to develop efficient mental strategies for computation with larger numbers without a calculator <ul> <li>partitioning using materials and part-part-whole diagrams to develop subtraction facts related to addition facts, such as 8 + 7 = 15 therefore 15 − 7 = 8 and 15 − 8 = 7</li> <li>using partitioning to develop and record facts systematically (for example, ‘How many ways can 12 monkeys be spread among 2 trees?’, 12 = 12 + 0, 12 = 11 + 1, 12 = 10 + 2, 12 = 9 + 3, …), explaining how they know they have found all possible partitions</li> <li>understanding basic addition and related subtraction facts and using extensions to these facts; for example, 6 + 6 = 12, 16 + 6 = 22, 6 + 7 = 13, 16 + 7 = 23, and 60 + 60 = 120, 600 + 600 = 1200</li> </ul>

Scoot Your Way Through Triple Digit Subtraction with Regrouping!

Say hello to Subtraction Strategy Scoot!– your new go-to task card kit that’s about to make your students’ subtraction skills soar! As an educator, we know you have a lot on your plate. That’s why we wanted to lend a helping hand by creating task cards tailored explicitly to your needs.No matter if you’re a seasoned pro or just starting, our mission is to help you engage your students, get them up and moving, and grow them into top-notch mathematicians.

Picture this: you’re wrapping up your unit on subtraction with regrouping, and you just can’t bear to whip out another 3-digit subtraction with regrouping worksheet PDF, so you need something different. That’s precisely what these task cards are here to help you with. This grouping of task cards contains 24 handy-dandy problems that encourage your students to get up and practise by playing a riveting game of Scoot!

Drop Those Subtraction With Regrouping Worksheets!

You don’t need another worksheet to practise subtraction strategies. Why not have your students get up and scoot across the room to show off their skills? It’s much more engaging and stimulating than sitting in a chair solving problems.

This get–up–and–go activity makes subtraction practise a breeze! This visually appealing set of task cards is the perfect tool to use any time of the year. To use this resource,

Hang the numbered task cards around the room and provide each student with a recording sheet.
Have a student stationed at each card and have them answer that question. Once they have responded to the question, tell the students to SCOOT!
Students will move to the next numbered card in order, repeating the process until they complete all the cards.
When complete, review the questions together or have students self-check using the answer key.

Through this activity, students will show their ability to solve triple-digit subtraction problems using place value strategies and practise checking their subtraction work using addition.
