# Mental Mondays #14

This starter idea focusses on 2D Shape. In particular the properties of shape and the correct use of shape related vocabulary. Like most of our mental and oral starter ideas it can be used as a group or individual activity too.

It is related to the "Target Board" activity we explored in Mental Mondays #13

Here's how this one works. You show a grid of 30 numbered shapes:

Then ask children to write on mini-whiteboards the identification numbers that refer to particular shapes they can see on the grid, for example:

- A pentagon...

- A regular pentagon...

- A parallelogram...

- A shape with only one line of symmetry...

Clearly, the statements can be as complex or as simple as necessary. As we said in the description of our last Mental and Oral activity, the power that drives the learning here is in the discussions that the children have about what they are doing.

Many other potential statements can be created:

-  A hexagon with a right angle...

-  An octagon with only one line of symmetry...

-  Two pentagons where the identification numbers sum to 26...

And of course, the children could be encouraged to play their own version of "I'm thinking of a shape..."

The attached file is a large (1200 x 998) .jpg image of the 30 shapes, so you can use this as part of a PowerPoint, or display it directly on an IWB.

### Perfect! I really needed a

Perfect! I really needed a grid of a good variety of 2D shapes, for an initial assessment activity. This looks like it will do the job perfectly. Thanks!

### Used this once again. Such a

Used this once again. Such a simple yet versatile resource! Excellent for discussing shape. Also, asking children to generate their own appropriate questions is a good assessment tool.

I will this as OMS first, but also like the sound of the sorting idea.

### Used this as a starter on

Used this as a starter on the IWB with my Year 6 class.  They had to jot the numbers on whiteboards of shapes that fitted my criteria.  Could quickly identify who had problems and which areas needed more focus - concave was quickly picked up but symmetry a definite weak spot!  Kids enjoyed it and it really emphasised that not all shapes look like the regular ones in the shape box!

Exactly what I was after, thank you.  Have been looking for some decent mental and oral starters for shape.

### This activity also lends

This activity also lends itself to a sort activity, where students will be given the cut up squares (shapes) and asked to sort them , then explain to their partner how they sorted. . .and then asked to sort them again!

### igoldman, That's a great

igoldman, That's a great adaptation for this resource. I love that the activity is so open-ended. Great maths, great language work, great problem solving / thinking skills. Thanks for sharing your idea and for your feedback. We'll look into adapting the layout of the shape images to make them easier to cut out.

Cheers, John

### I am searching for problem

I am searching for problem solving activities for our summer program, and these are exactly what I am looking for.  I saw this first on Pinterest, and then followed the link to your site.  Thanks for this gem!

### Great resource, lots of

Great resource, lots of potential opportunities with this target board, I think I will use it with differentiated questions for 3 levels for a starter as it lends itself easily to this. Thank you.

### Im going to try and use this

Im going to try and use this tomorrow to play shape 'Guess Who' with the children. Such a handy resource, thanks :)

Just downloaded this for a mental oral starter tomorrow! Will give the chn plenty of opportunity to practice the language they have learnt today and will engage them as they will play a guessing game :-)  Thank you!

### Could also use this as a more

Could also use this as a more open ended mental and oral starter - for example "Which shape is the odd one out in row 3 and why?" - hopefully would produce lots of mathematical dialogue on proprties of shapes perhaps extending to 3D shapes eg shape 4 is the odd one out because it is the only shape on the base of a prism etc. You could hide a shape and children have to guess what's hidden - or just partially reveal a shape and children have to discuss what the shape might be from just viewing a corner. Very useful resource, many thanks.

I think I'll be using this as a guided group activity first and then as mental maths or morning maths (year 2)

### Fantastic resource.I have

Fantastic resource.I have spent many evenings looking for decent shape resources to use with my yr.4 class and have found myself making resources over and over again. This shape grid serves many purposes and is now a well visited file on my computer. Thank you.
