Arithmetic

 

Have a go at the 2019 KS1 SATs Arithmetic paper below.

Monday

WALT: measure length in cm.

 

 

Tuesday

WALT: compare lengths.

Wednesday

WALT: use the four operations (+ - x ÷) with length.

Thursday

WALT: compare mass.

 

How do we compare the mass of objects?

When comparing the mass of objects, we use these words:

  • heavier and heaviest

  • lighter and lightest

 

Top tip

Remember an object can be heavier than something else, even if it looks smaller. The mass of two objects might be equal to each other, too.

Using scales

 

Here is a set of scales with 2 apples and 3 oranges. You can see which is heavier by which way the scales are tipping.

  • The 3 oranges are heavier than the 2 apples. When something is heavier, we say it weighs more.

  • The 2 apples are lighter than the 3 oranges. When something is lighter, we say it weighs less

 

Using symbols

We can use the symbols for more than and less than to compare the mass of objects.

  • > means more than

  • < means less than

  • = means equal to or the same

Friday

WALT: solve puzzles and problems!

Think of all the different coins you could use to make 6p. For example, you couldn't use a 10p as that is greater than 6p and she paid the exact amount.

 

You could use 6 x 1p coins e.g. 1p + 1p + 1p + 1p + 1p + 1p = 6p

 

Can you find the other 4 ways of making 6p exactly?

 

*Challenge - What if the gobstopper cost 7p? How many different ways could you find to make 7p?

Can you complete the crossword? For example, 1. Across is 7-5 which would equal 2. You would then write the number two in words in the crossword.
