This is five different Número del día warm-ups that become progressively more difficult. The idea is to allow children to represent a number in a variety of ways to practice concepts such as place value and money. Cut these sheets in half and use these warm-ups once a week as a formative assessment as well as a teaching tool.
Every month or so the whole class can work on a more difficult version or you can differentiate your instruction by allowing certain groups of students to work on an easier or intermediate version while other children work on the most difficult version of the activity.
I allow my students to choose between two different numbers for the activity - usually a two or three digit number at the beginning of the year and a three or four digit number by the end of the year; choosing different numbers allows for further differentiation. Students love to practice these activities on a regular basis because each week they become more confident; for example, students can easily explain that 265 has 26 tens after visually representing the number as hundreds, tens and ones blocks.
This activity is a great formative assessment because you can easily form strategy groups based upon what the students complete independently or with difficulty. Enjoy!
