This task supports students in correctly writing numbers. Because students have to trace the number, instead of coloring in a bubble with the number in it or circling the correct number, they gain handwriting practice as well as counting and addition practice.

This game will reinforce number before and after as well as reading and sequencing numbers.

This task aims to give students practice counting and recording the given number on quantities up to 20.

Module 1 sets the foundation for students to master the sums and differences to 20 and to  subsequently apply these skills to fluently add one-digit to two-digit numbers at least through 100 using place value understandings, properties of operations and the relationship between addition and subtraction.

Print out these colorfully illustrated PDF file pages to practice matching the number and the number words for 1-20. Cut the cards in two parts. One side has the number while the other side number word. Put them in a math center. Laminate them and they will last even longer.

Print out these colorfully illustrated PDF file pages for each of the numbers 11-20. Each card shows the numeral and clever art work that shows the amount for that numeral. Below that is a work area to practice tracing over the numerals with arrows that show how to form each numeral.
