Monday's maths
Date: 11th May 2020 @ 7:51am
Happy Monday!
Today we are going to focus on adding 3, 1 digit numbers together.
Sometimes it easier to use the number facts we know to help solve trickier problems. We can count on using a number line, use concrete objects or count on but there are other strategies we can use that are much faster and much more effective.
Look at this addition 2+5+8=
Ask yourself the following question. Can I see 2 numbers that when added together make 10?
Then re -arrange the addition sentence so that the 2 numbers that add to 10 are together
8+2+5= We know that 8+2=10 and 10+5=15
Use a number line to help you !
Have a go for yourself
Challenge 1
1. 7+5+3= 2. 1+4+9= 3. 8+3+2= 4. 6+1+4= 5. 8+5+5= 6. 4+10+6= 7. 9+9+1= 8. 10+10+10=
Challenge 2
Can you read the questions and then write the number sentence to represent it, remembering to use the correct formation!
1. James bought 7 red cars, 4 blue cars and 3 yellow cars. How many altogether?
2. Kirsty bought 2 pink cakes, 7 yellow cakes and 3 blue cakes. How many altogether?
