Level 3 – Number
Addition and Subtraction
Loop Cards are a great way to engage your whole class in a fun and challenging activity!
These Loop Cards are created for use in the ‘Fluency’ component of an iSURF lesson, based on addition/subtraction. Loop Cards are a great way to start a class discussion about the most efficient strategies for mental computation.
Print Loop Cards onto coloured cardboard, laminate and cut around each card.
How to use in the classroom…
• share out loop cards (28 in total) amongst whole class (if there are extras – give two to students with start/end cards and then others. Cards must all be in use for the loop to be complete)
• set your stopwatch to 00:00:00. When ‘start’ is called, begin timing
• ask the student with the start card to say ‘start’ and then read their question out
• the class (mentally) works out what the answer will be and checks their own card
• if they believe their card has the correct answer to the question asked – they call out the answer
• if there are no immediate objections to their answer, they ask the question on their card
• objections can be lodged by calling out ‘OBJECTION’ - the clock is stopped. The objection is discussed. If correct - the clock continues, if incorrect – 10 seconds is added to the final time
• the cycle continues, until the last answer is given and the card with ‘END’ is reached
• record the time and try to beat it each time you use this set of Loop Cards.
* Individual students, in need of extra practice or extension, can complete the cards by themselves.
* Loop Cards can also be used as a ‘pre’ and ‘post’ assessment tool to gather anecdotal evidence about how a class/individual is travelling with the concept you are currently teaching.
* Cards towards the end of the set may be more challenging. Identify these with a small mark/sticker and distribute to students in need of extension.
* If using multiple sets of Loop Cards in the classroom (each with a different concept), copy them onto different coloured cardboard to ensure they do not get mixed up.
