This file includes 2 different activities that are great for your maths warm ups.
Activity 1: 1-20 Number strip - Print off 1-20 for each student. I printed on bright coloured paper. Cut up the numbers and put them in a little bag. Each student gets a bag for the warm up activity. Students can put them in order from 1-20 or start form 20 and go backwards. Call out a number and students have to find that number and then continue putting the numbers in the correct order. There are lots of different ways these number cards can be used.
Activity 2: Missing Numbers 1-20 - Print off all of the cards and laminate. I printed 2 to a page to make them a bit smaller. There are 21 different cards included. Each card has 9 numbers missing for students to work out and write on using a whiteboard marker. If students are still struggling with numbers 1-20, give them a number line (or print off the umber strip and do not cut it up).
If you want to use these as activity sheets, just print and not laminate. They can be used as exit slips, just print them 4 to a page to shrink them.
