Math Center: Number Sense Basics – Ten Frames and Tally Marks is a matching activity designed to build a conceptual understanding that amounts can be represented in many ways. The cards are specially designed so that students are required to mentally switch between different concepts as they endeavour to find a complete match. This requires a higher level of thinking than simply using the same visual representation. These cards assist in developing mental computational fluency in young learners, creates flexibility in counting and is an ideal resource for independent math centers or math station rotations. Instructions: Print, laminate and cut the individual cards. Mix the cards. Using the imbedded arrows, students create matches of three. Cards can be divided into as few or as many sets as required. This resource contains: 61 cards / 20 matches (3 cards to a match) and one title card. PDF and PNG files. Enjoy!

Balancing Equations – Intro to Switching Concepts are task cards designed to provide students with opportunities to improve their understanding of a range of mathematical concepts. Students need to find the total of all three boxes before being able to determine the number which balances both sides. The cards are specially designed so that students are required to mentally switch between different concepts several times for every card. This requires a higher level of thinking than simply calculating totals that continuously use the same visual representation. This resource is aimed at Year 2 and 3 students but is also useful if you have purchased any of the higher levelled balancing equations resources and need something at a lower standard for differentiation. The concepts included in the cards: Multiplication arrays Multiplication equal groups Repeated addition Pictorial representations of base ten blocks (single and double-digit numbers) Doubling Halving Although these cards are commonly used as task cards, they have also been used successfully in math centers or rotations. This resources contains: A total of 25 cards (24 task cards and 1 title card) Student recording sheet Answer key Complete PDF and individual PNG files of the cards also included Instructions: Print, laminate and cut the individual cards. (p. 2-8) Print student sheet (p. 9) and provide each student with a worksheet. Distribute the cards around the room Students may start at any number and work their way through in any order Check answers Enjoy!

Geography/Math Center: Rivers, Deserts & Mountains is a fun, matching activity which can be used as a either a geography or math center. As a geography center students match the river, mountain or desert with its size and its geographical location. As a math center students create matches by sorting out the measurements from longest to shortest for the rivers, largest to smallest for deserts and highest to lowest for mountains. The Rivers 1st - 8th longest in the world: The Nile, The Amazon, The Yangtze, The Mississippi, The Yenisey, The Yellow, The Ob, La Plata The Deserts 1st - 8th largest in the world: Antarctic, Arctic, Sahara, Great Australian, Arabian, Gobi, Kalahari, Patagonian The Mountains 1st - 4th tallest in the world : Mount Everest, K2, Kangchenjunga, Lhotse This resource contains: 60 cards (20 matches). The measurement cards all contain both forms of measurement (e.g., mi and km) PDF and PNG files. Instructions: Print, laminate and cut the individual cards. Mix the cards. Using the imbedded arrows, students create matches of three. Cards can be divided into as few or as many sets as required. Enjoy!
