Description: Add & Subtract Decimals – Calculating Sales & Profits Boom Cards includes 2 sets of fill-in-the-blank styled, interactive, self-checking digital cards. The cards provide students with opportunities to improve their skills in adding and subtracting decimals. The context is related to a fictional store called Abracadabra Antiques which sells antiques. For the addition cards, students are required to add the sales from the store’s morning and afternoon sessions. For the subtraction cards, students are required to subtract the cost price of an item from the price from which it was sold, thus working out the profit for the day. Students will add and subtract both double and triple-digit numbers using 2 decimal places (appropriate for money). At times, a product has been sold more than once in a day so students may find themselves drawing on a variety of mental computation skills such as doubling, halving, compensating (rounding then adjusting) and multiplying by 10 by adding an extra zero. Although it is possible for high achieving students to mentally calculate the totals, it is more than appropriate for them to use a pen/pencil and paper to make the calculations necessary. This resource contains: - 2 sets of Boom Cards with 24 questions per set - Answer keys are provided on the last card of each set (card 27) Enjoy!
