22.02.21 - Multiplication

This week, we will be learning about formal multiplication methods.

 

Monday 22nd February:

Task 1: Spend 5-10 minutes practising your times tables on TTRockStars.

Task 2: To use the formal method for multiplication [TO x TO - grid method]

- This lesson focuses on using the grid method to multiply two 2-digit numbers together. Understanding this method before using the expanded or compact column method helps you to be able to see all the different parts of the calculation that need doing. 

- Miss Churn will be focusing on this method and associated skills in the Zoom lesson, but you can also watch a recap of the method by clicking here.

- After the lesson, have a go at completing the activities below. All resources are available at the bottom of this page. 

  • Must: Complete Challenge 1, and Challenge 2 a-l (if this is a looks a bit tricky, you can start with the Support sheet available below).
  • Should: Complete Challenge 1, and all of Challenge 2.
  • Could: Complete Challenge 1, Challenge 2 and Challenge 3.

 

Tuesday 23rd February:

Task 1: Choose and play a game from the 'Play' section on Mathletics.

Task 2: To use the formal method for multiplication [HTO x TO - grid method]

- This lesson focuses on using the grid method to multiply a 3-digit and a 2-digit number together. Understanding this method before using the expanded or compact column method helps you to be able to see all the different parts of the calculation that need doing. 

- There isn't a Zoom lesson for Maths today, however Miss Scott has recorded a video lesson for you to access by clicking here. In the video lesson, Miss Scott focuses on the grid method and associated skills, but you can also watch a recap of the method by clicking here.

- After you have watched the video lesson, have a go at completing the activities below. All resources are available at the bottom of this page. 

  • Must: Complete Challenge 1 (if this is a looks a bit tricky, you can start with the Support sheet available below).
  • Should: Complete Challenge 1 and Challenge 2.
  • Could: Complete Challenge 1, Challenge 2 and Challenge 3. (Extension: for a little more challenge, have a go at the Extension Sheet available below).

Wednesday 24th February:

Task 1: Spend 5-10 minutes practising your times tables on TTRockStars.

Task 2: To use the formal written method for multiplication [TO x TO - written method]

- This lesson focuses on using the formal written method to multiply two 2-digit numbers together. Now that you understand the grid method and the different parts of the calculation, we can move on to the expanded or compact column method. 

- Miss Scott will be focusing on this method and associated skills in the Zoom lesson, but you can also watch a recap of the method by clicking here.

- After the lesson, have a go at completing the activities below. All resources are available at the bottom of this page. 

  • Must: Complete Challenge 1 (if this is a looks a bit tricky, you can start with the Support sheet available below).
  • Should: Complete Challenge 1 and Challenge 2.
  • Could: Complete Challenge 1, Challenge 2 and Challenge 3. (Extension: for a little more challenge, have a go at the Extension Sheet available below).

Friday 26th February:

Task 1: Complete the set activities on Mathletics

Task 2: To solve word problems involving multiplication.

- In today's lesson, you will be using the different strategies and methods for the four operations that you know to solve word problems. Some of the questions are one-step problems and others may have two or more steps to solve.

Click here to watch a video in which Miss Churn talks through some of the strategies that might be helpful for you to use today.

- Follow these tips to help you solve each of the problems:

  1. Read the question carefully and make sure that you understand what the question is asking for. It might help to ignore the numbers to start with whilst you ensure that you understand what the problem is looking for as an answer.
  2. Develop a plan of action. You could draw a picture or diagram to help. Think about these questions as you create your plan: will the answer be a bigger number or smaller number than what the problem started with? This will help you to decide whether to use addition/multiplication or subtraction/division. Then consider whether the different groups/numbers are all the same (equal) or different. If the groups are different, you will probably use addition or subtraction. If the groups are the same, you will probably use multiplication or division. Remember, sometimes you may have to do more than one operation to solve a question.
  3. Carry out your plan - use the strategies you know to find answers to each part of the problem.
  4. Check your answers - work backwards now using inverse operations or work through the problem again using different methods. Once you are happy, write your answer as part of a sentence and make sure it answers the problem that the question was asking for.

- Check back here on Friday where there will be a supporting video for you to watch created by Miss Churn.

  • Must: Complete Challenge 1 and Challenge 2 (a-d).
  • Should: Complete Challenge 1 and Challenge 2.
  • Could: Complete Challenge 1, Challenge 2 and Challenge 3.
