Sparrows

Monday 18th January 2021

 

Morning sparrows! 

 

Well done for all your hard work on length and perimeter so far. In today's lesson, you will be applying the skills you have learnt during this unit to solving problems.

 

 

When problem solving, one of the most important things to remember is to read the question carefully and to think it through before jumping in. You may need to take note of the units of measurement and representing the question using pictures or bar models may help you to understand what you need to do. Try your best, and don't rush! 

 

 

So that you can see how I would work out each question (and so you can check your answers), I have uploaded a video going through most of the questions. The video does not include the final question, however I have added an additional slide to go through the answer to that one. 

 

Please do not hesitate to contact me via Dojo if you are unsure of anything or have any questions. 

 

Keep up the great work!

Morning sparrows! 

 

Well done for all your hard work on length and perimeter so far. In today's lesson, you will continue to work on finding the perimeter, this time of rectilinear shapes. A rectilinear shape is a shape that has straight sides and right angles. It can look like two rectangles that have been joined together.

 

Watch the video carefully and work on the questions as you go along. This is a really valuable way of practising the skills you need before you complete your independent work. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.   

 

Please do not hesitate to contact me via Dojo if you are unsure of anything or finding this too challenging.

Morning sparrows! 

 

It is great to see your confidence with finding the perimeter growing. Well done for all your hard work. In today's lesson, you will continue to work on finding the perimeter of rectangles. Remember, if you are finding the perimeter of a rectangle, you only need to add 4 measurements (or 2 if you then multiply the total of those 2 sides, by 2!)

 

 

For example, you could calculate the perimeter by doing 2cm + 6cm + 2cm + 6cm =16cm or you could do 2cm + 6cm = 8cm then 8cm x 2 = 16cm. This works for a rectangle because rectangles have 2 pairs of equal sides. 

 

Watch the video carefully and work on the questions as you go along. This is a really valuable way of practising the skills you need before you complete your independent work. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.

Morning sparrows! 

 

Well done for your great work yesterday with finding the perimeter by measuring. This was recapping the skills you learnt last year, which we are going to build on today. In today's lesson, you will be using a grid to find the perimeter of irregular shapes. 

 

Watch the video carefully and work on the questions as you go along. This is a really valuable way of practising the skills you need before you complete your independent work. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished. Try to find multiple possibilities for the final question, rather than just stopping at one!  

 

I look forward to seeing your fantastic work on Dojo.

Perimeter on a grid

Morning sparrows! 

 

Well done for your great revision of adding and subtracting lengths. You will have had to use your skills with converting units of measurement (e.g. mm to cm and mm), which is an important life skill! Today, your lesson will be recapping how to find the perimeter, so that we can build on that learning later in the week.  

 

Watch the video carefully and work on the questions as you go along. This is a really valuable way of practising the skills you need before you complete your independent work. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished. If you are unable to print off the worksheet, then you may want to find the perimeter of objects in your house rather than measuring the rectangles that are on the sheet. For example, a post-it note, a letter etc. 

 

Finding the perimeter is a fun skill to practice at home. For example, you might like to find out the perimeter of your favourite book, or a £5 note! 

 

I look forward to seeing your fantastic work on Dojo.

 

Have a good day!

Morning sparrows! 

 

Well done for a fantastic week of home learning last week. You have made a great start to your new unit of length and perimeter. Today you are going to be continuing to recap calculating with lengths. On Friday you were adding lengths, therefore today you will be subtracting lengths.   

 

Watch the video carefully and work on the questions as you go along. This is a really valuable way of practising the skills you need before you complete your independent work. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.

 

Keep up the great work sparrows. I look forward to seeing your wonderful learning on Class Dojo.

Subtract lengths

Friday 8th January 2021

 

Morning sparrows!

 

Well done for doing so well with your kilometres work yesterday. You really applied your knowledge from earlier in the week and used it in your new learning about kilometres. Today, we are moving onto looking at calculating with measurements. We are going to start with recapping adding lengths in mm, cm and m. You will need to use your skills from our previous unit looking at addition and subtraction, and applying that to your new learning about the relationships between units of measurements. 

 

Remember:

10mm = 1cm

100cm = 1m

1,000m = 1km

 

Watch the video carefully and work on the questions as you go along. This is a really valuable way of practising the skills you need before you complete your independent work. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.

 

Happy Friday and enjoy your well deserved weekend.

Morning sparrows!

 

Thank you for sending me your work recapping the relationship between mm and cm. It was good to see that you have retained a lot of your knowledge on this topic from last year, and that you are confident with converting between the two units of measurement. Today you will be looking at kilometres. You wouldn't have looked at kilometres too much in year 3, but with the understanding of "kilo" meaning 1,000, I am confident that you will do brilliantly! 

 

10mm = 1cm

100cm = 1m

1,000m = 1km

 

Watch the video carefully and work on the questions as you go along. This is a really valuable way of practising the skills you need before you complete your independent work. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.

 

We're all so proud of you. Please let me know if you need any help and I'll do by best to guide you remotely.

Morning sparrows!

 

Well done on your work yesterday recapping the relationship between cm and m. You showed a great understanding, which will really help you as we progress through this unit of work. Today you will be looking at the relationship between mm and cm. The video goes into detail about link between mm and cm, so make sure that you are engaging with the video and working on the questions as you go along. This is a really valuable way of practising the skills you need, before you complete your independent work. 

 

Please watch the video and complete the questions you are asked to do. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.

 

Keep up the great work! Tomorrow we will be using this existing knowledge to look at kilometres. 

 

Have a great day!

Equivalent lengths mm and cm

Tuesday 5th January 2021

 

Morning sparrows!

 

Today, you will be starting your new unit looking at length and perimeter. To help us recap last year's learning, we will be looking today at equivalent lengths (m and cm). Increasing our confidence with how to measure length and the relationship between mm, cm and m will help us when we come to using these measurements to help us calculate perimeter. 

 

Please watch the video and complete the questions you are asked to do. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.

 

Well done to those of you who submitted fantastic maths learning yesterday. It has been wonderful to see how engaged you are in your own learning from home.

 

Have a great day!

Equivalent lengths m and cm

Monday 4th January 2021

 

Morning sparrows!

 

Today, you will be looking at ways to check your addition and subtraction calculations. This will focus on using the inverse to work backwards from the solution. You were first taught about using the inverse to check calculations in Years 1 and 2 with simple calculations such as 3 + 4 = 7 which can be checked using the inverse calculations of 7 - 4 or 7 - 3. You will now be applying this method with 4-digit numbers.

 

This lesson is also an important opportunity for you to revise the formal column methods of addition and subtraction.  

 

Please watch the video and complete the questions you are asked to do. You will probably need a scrap piece of paper or you could use the back of your worksheet.

 

Once you have watched the video, please complete the worksheet. I will upload the answers so that you can check your work once you have finished.

 

Well done for being super, independent learners. Please upload a photo of your worksheet onto Class Dojo so that I can see how well you have understood today's lesson.
