Measuring for the Art Show

Today we started a new unit that will help us transition from our recent unit on Measurement back into working on addition and subtraction.  We will be focusing on using 'friendly numbers' and the number line to develop efficient operational strategies. 

At home, practice counting by 10s - starting at different numbers.
For example,
Let's count by 10s (adding 10s), starting at 4: 4, 14, 24, 34, 44, 54, 64, 74, 84, 94, 104,...

Remember to also practice subtracting 10s, too.
For example,
Let's practice subtracting by 10s, starting at 98: 98, 88, 78, 68, 58, 48, 38, 28, 18, 8.
