From that moment on I vowed to not make assumptions about what students can or cannot do.

Are there any special ones? An investigation looking at doing and undoing mathematical operations focusing on doubling, halving, adding and subtracting. Can you find out their scores? What can change and what has to stay the same so that … is still true? This problem challenges you to find out how many odd numbers there are between pairs of numbers. What Could It Be?

They can engage deeply with innovative “Live” problems that make math both social and conceptual; kids can work together on solutions and must recognize there are multiple ways to get the same solvint. What would the solution be in each case? Does it matter if you go first or second? What parents need to know Parents need to know that NRICH’s free K math activities require kids to use mathematical thinking; this type of problem solving can take a while, so encourage kids to ,ey with it.

Can you say why this is special? Working on the problem will usually involve using one or several problem-solving skills such as: Secret Number Age 5 to 7 Challenge Level: The skills needed for a problem-solving task By this we mean the problem-solving skills listed above in Stage 2: Can you go through this maze so stwge the numbers you pass add to exactly ?

Site based on PBS show is online learning at its best. The answer is To support this aim, members of the NRICH team work in a wide range of capacities, including providing professional development for teachers wishing to embed rich mathematical tasks into everyday classroom practice.

How many circles would I need to make the next size up for each? As teachers we can support our students to develop the skills they need to tackle problems by the classroom culture we create. You might like to draw a diagram, act it out or represent it with a model. This will give you the opportunity to share good practice across the school as well as support each other in developing high-quality mathematics classrooms.
