Some "Power Equations" , equations with indices, or whatever you like to call them. (And so detached from posting here I realise I don't have a clue what hashtag to use... 😐) Downloadable version with worked solutions here: kshancock.co.uk/lessonresour...

A white page showing four handwritten algebra questions, each inside a red rectangular box, about solving equations using indices.
The first box reads: “Solve: 3 to the power 2x squared times 27 to the power 2x squared times 21 to the power x minus 1 equals 7 to the power x times 3 to the power 6, all over 63.”
The second box reads: “Solve: open bracket 4x times 2 to the power x close bracket squared, times 100 to the power x, times 2 to the power 14 equals 5 to the power 2x over 2 times 4 to the power 2x.”
The third box reads: “Solve: 9 to the power three quarters times 5 to the power x times seven fifths equals 3 times the square root of 21 times 35 times 5 to the power x plus 1.”
The fourth box reads: “Solve: 5 to the power minus x squared times 6 to the power x times 10 equals 2 to the power x plus 1 times 3 squared times 25 to the power minus x plus three halves.

A new A level task. Really enjoyed watching the students think about this one: kshancock.co.uk/aleveltasks.... #MathsToday

A blank parametric equations worksheet displayed as a table. Columns are titled: x = p(t), y = q(t), Cartesian Equation f(x,y), Intersection with axes, Constraint on t, Domain, Range, and Sketch. Five rows contain given parametric pairs such as x = 3 – t, y = –4 + 3t; x = 3t², y = 6t; x = 4 cos t, y = 2 sin t; x = 1 + 2 cos t, y = 3 + 2 sin t; and x = e²ᵗ, y = e³ᵗ, with remaining columns left blank for students to complete

second blank parametric equations worksheet in table format. Columns match the first sheet: x = p(t), y = q(t), Cartesian Equation f(x,y), Intersection with axes, Constraint on t, Domain, Range, and Sketch. Five rows include parametric definitions such as x = t² – 1, y = t(t² – 1); x = 3 cos 2t, y = 2 cos t; x = 1 + 2t², y = –3 + 4t; x = ln(t – 2), y = 1/(t + 1) with t > 3; and x = cot t, y = 3 sin t for 0 ≤ t ≤ π, with other columns empty for completion.

I'm in the last session - talking about how/why I use and design these, if you are interested. #MathsConf39 @lasalleed.bsky.social

Maths worksheet focused on estimation. The left side shows a worked example estimating the value of (3.45 × 42.3) ÷ 2.1 as approximately 3 × 40 ÷ 2 = 120 ÷ 2 = 60. The right side poses three reflective questions: the meaning of the ≈ symbol, the use of the equals sign in the second line, and how the estimation would change if the denominator were 7.1 instead of 2.1.

In #MathsToday (ish - probably last week actually) some activities with Surds. Answers and better quality versions on the website links. kshancock.co.uk/lessonresour... kshancock.co.uk/lessonresour...

Maths worksheet titled 'Multiplying surds'. Students are instructed to pair surds from a 3x4 grid (including values like √7, 2√3, √48, etc.) to match answers in boxes below (e.g., 14, 6√7, 20√7, 144, 60√2, 21√10). A crossed-out calculator icon indicates calculators are not allowed.

Maths worksheet titled 'Fully factorise'. It includes an example: √2y − √50x = √2(y − 5x), followed by four expressions to factorise: √3x + √75, √98 + 4√2x, √48 + √12x, and √32y² + √18xy."

In #MathsToday (well the highlight of this week) A few nice tasks with my Lower Sixth FM task. This one certainly challenged them more than I thought on their rules of indices Pdf available on this page: kshancock.co.uk/aleveltasks....

A selection of expressions in boxes which students have to multiply to find matching products.

If you are starting planning for the new term, I've collated all my worked examples in one place.

Karen@karenshancock.bsky.social · last yr.

I've done some work on collated my worked examples over the holidays. Here's the database of those I've created over the past few years. Perhaps you can make use of them in your teaching too? kshancock.co.uk/workedexampl... #UKMathsChat

Which fjords would you find the mean of in part (b)? #UKMathsChat #ITeachMath

A grouped frequency table of fjord lengths (from 0km to 250km)
(Source: https://en.wikipedia.org/wiki/List_0f_Norwegian_j0Ms)
(a) Work out the number of fiords that have a length of at least 100km.

(b) (i) Calculate an estimate of the mean length of these fiords.
Give your answer to 1 decimal place.

Temporary lights near me... They are the non cyclist friendly lights where there isn't sufficient time to get through the stretch on a green light and the oncoming traffic can't really see you either so they automatically cause cyclist/car driver confrontation.

"Rationalise the denominator on..." or "Rationalise the denominator of..." I realised today I always say the first. I'm off to check some older textbooks - but wondering if I just misheard at some point and it stuck... #UkMathsChat

Tonight's crafting. :-)

This was a fun tutorial to follow. #Painting

A water colour painting of what could be two koi carp or two goldfish.

I guess wearing them to take down the decorations is better than not wearing them at all until December. New socks. #knitting 🧶

@studymaths.bsky.social I'm attempting a pizza party without a pizza oven and in my, not very large, flat rather than a garden... I've run out of space already!
