'Taught right, every maths pupil could be a Countdown winner' In 1997, James Martin, a quietly unassuming Oxford maths PhD, entered television gameshow folklore with his stunning solution to a maths problem on Countdown. The challenge: make 952 using the numbers 100, 75, 50, 25, 3 and 6. You may use the four standard operations of addition, subtraction, multiplication and division. You do not have to use all the numbers and you cannot use the same number more than once.

Assessment tasks Pupils use mathematical reasoning to estimate the number of descendants a girl who lived 110 years ago might have today. Suitability National Curriculum levels 5 to 8 Time 1st Grade Story Problems Tomorrow I go into a 1st grade classroom to teach a lesson on addition and subtraction story problems. This Investigations lesson for the day centers on students solving these 6 problems, however I am looking to change it up a bit. While reading my CGI book, Children’s Mathematics, to learn more about the trajectory in which students solve these types of problems, I found this diagram really helpful and interesting…. I went into this planning thinking I was going to be looking for how students combined numbers in the context of the diagram above. From there, I was planning to have students do a structured share of their strategies, comparing and contrasting along the way.

The 5-4-3-2-1 Challenge from Will Shortz and NPR On Sunday morning, Nancy Swank tweeted me a link to a puzzle on NPR's website. This shouldn't come as a surprise because Nancy is the entire reason why NPR spent an entire day in my classroom in 2014. I followed the link and started reading the puzzle. Within about a minute, I knew I HAD to do this puzzle with my students this week. Here's the link to the puzzle from NPR so you can check it out yourself. I'm naming this puzzle the "5-4-3-2-1 Challenge."
