As we come to the end of week 3, we are now almost halfway through our second topic, Whole Numbers 2. Important points for Friday would be:
- When asked to estimate 3479 x 32, we look at the numbers and find out what is the greatest place value for the numbers respectively.
- 3479 is up to thousands, therefore we round the number to the nearest thousand.
- 32 is up to tens so we round the numbers to the nearest tens.
- 3479 is approximately 3000 and 32 is approximately 30.
- 3000 x 30 = 3000 x 3 x 10 = 9000 x 10 = 90000
We also went through 4 questions of our enrichment book. We learnt about the skill of using 'Guess and Check' to solve word problems. On Friday, we looked at the importance of model drawing. Model drawing is especially useful when we need to compare items and drawing the models will be able to help you visualize better. Key important points would be for you to draw neatly using a ruler and label the models.
Next week will be a short week and there will be NO enrichment lessons, therefore, remember to finish questions 3 - 6 of the enrichment worksheet for Whole Numbers so that we can go through during lesson on the following Friday.
Sincerely,
Mr Nelson Ong
