## Objective

SWBAT read and write numbers to 30.

#### Big Idea

First graders must build fluency in writing their numbers from 1 to 120. This ability is built through sequential small steps and repetitive practice.

## Rev Them Up

5 minutes

It's time to get them thinking about math.  Here is a great activity to get them thinking, listening, and focusing.

Pick a student to start with in the room and ask that child to begin a counting chain for the class to follow.  This child will start with saying "one" and then the next child "two" and so on.  Have the chain continue until they reach 30.  If anyone strays or breaks the chain, pick a start over point and have a new child begin the chain.

## Whole Group Interaction

8 minutes

We will be using calendar board numbers today and putting them in order in small groups.  I have several collections of calendar board numbers from over the years and this will a great way to use them as a math tool.  I will gather up enough sets for five groups.

If you do not have these or do not want to use them, it would be fine to type your numbers and print them out, but I would pre-cut them and have them ready to go.  You want your lesson to have enough time and focus on placing them in order, not having them prep their own numbers.

Your students may have already mastered writing their numbers 1-20 in Kindergarten, so this lesson will be quick and easy. Also, make sure to cover the lesson here on reading and writing their numbers to 20 before you complete this lesson.

I want my students practicing writing their numbers with accuracy and begin to notice there is a structure to our numbers and a pattern appears. (MP7). I want students to see that there is a structure they can use to write the numbers correctly by noticing that the number in the tens place for 11-20 is always a 1, while the number in the 1s place goes up in sequential order. This will help prepare them for work we’ll do in place value, too.I need them to be able to count to 120 before the end of the year and this is developed in small steps. (1.NBT.A.1).

I will instruct my students that I want them to work together to put the calendar board numbers in order.  I will ask someone in the group to pass the cards out equally to their group. I hope this ensures that the numbers are not automatically in order and they have to use reasoning to get them in order. Check the resource section for a video of the game in action.

## Independent Practice

10 minutes

Step 1: We will work as a whole class and number our page to 30 together.  I will do it with them from the Smart Board and they will copy onto their paper. If you have a word processing program, create a document with a table that contains 3 rows of 10. If you can only write on the chalkboard or plain white background, make sure to write numbers in sets of 10; first row 1-10, second row 11-20, third row 21-30. There is a structure and patterns to numbers and I want to make sure they begin to see this to develop their counting skills. (MP7). My focus will be;

Keep their numbers neat and when writing a double digit number, they should be side-by-side.

Point out the pattern that begins to form from top to bottom. Ex. 2 is above a 12 and 22 is below 12; 10, 20, and 30 are aligned with each other.

Point out the difference between a 2 and 5 and if they were to reverse one or the other, their audience would see it as the other number.

I will have them put their paper away and prepare for part 2.

## Independent Practice Part 2

10 minutes

Step 2: Students will be working together in a small group of 4 to 5 students to complete their "Pass the Paper" numbering page. Explain to them their group will be timed for one minute.  The first person writes a 1 in the first blank and then passes it to the person to their left.  This person writes 2 and passes. They keep passing until the group reaches 30.  The first group to get it done, wins! Look at the resources for videos of the game in action and for a picture of completed work.
