This is a set of 25 numbered (and repeated un-numbered) task cards with 25 different 1st grade math problems, aligned to Texas 1.3F, as well as worksheets to generate word problems based on number sentences. The task cards require the student to determine the missing number for basic three-digit addition and subtraction problems, up to 20. An answer key, as well as a blank test sheet, are also provided, as well as two posters for the Texas standard.
The task cards are as follows:
#1-5 - greatest number <10
#6-20 - greatest number 5-15
#21-25 - greatest number 16-20
The task cards tend to slowly get more difficult as you go through them.
The worksheets are for the students to generate word problems based on number sentences. There is a blank worksheet for the students to write their own number sentence and word problem, five different worksheets with number sentences already provided for the students to generate word problems, and a blank worksheet for the teacher to provide number sentences for the students to then generate word problems.
These task cards and worksheets are labeled as Texas 1.3F, with a cover sheet and the standard on each numbered card and worksheet. Common Core is NOT mentioned or referenced in this resource. If you would like these labeled as Common Core, various other State standards or unlabeled, I have these same task cards in these formats in other listings in my shop.
