Students construct sets of numbers up to 10, write the numerals up to 10, and count up to 10 rationally. They use ten frames and also make bean sticks.

I used this lesson to first build my students understanding of working up to 10. However, I knew they knew how to make 10, so to adjust this particular lesson, I then built on from this lesson. We used the strategy of counting on to work into teen numbers (designing the concept of ten and extra ones). This lesson mat with the fingers was great because kids could make their ten with the hands, but then also see the extra ones. I would only use this to make combinations up to 10, build the concepts of a group of ten and some extra ones, and counting on. I did not use the numeral cards as we were more focused on counting out groups of numbers, counting on from that group, building a ten, and seeing extra ones.

I used The Hungry Catepillar lesson from this link.

However I did an extension off this lesson using this resource to allow teachers to work on the skills of addition, the precise language of tens and some extra ones, and seeing groups of ten.

This activity is a great way to include Language Arts along with Mathematics. Using The Very Hungry Catepillar, we used based-ten blocks to place onto a ten frames. Each time the catepillar eats something, we add to the ten frame. At the end of the story, we look at how much the catepillar has eaten. However, I took this activity a step further to continue strengthening the use of addition. Students and I then had a variety of situations at the end of the story where the catepillar ate 4 more leaves. The students then add four more, either in a group of 4 or counting out 4 individual items. We then look again at using our language of, "I have a 3 groups of ten and 4 extra ones."

Challenges with this lesson is making sure the students have added a cube onto their ten frame for each item they ate. As well, students would have to also understand how to use a ten frame before the start of the lesson. As well, if you are working to be precise with the language of tens and extra ones, you want to nudge your students to use this language. You will want to model this multiple times.

In this lesson students will count quantities of objects by tens. Students will move from counting objects exclusively by ones to groups of tens and ones.

In this task, a group of children sit around a table. Without peeking, they figure out how many feet are under the table. They can use mathematical tools, such as cubes or drawings, that will help them.

I extended off of this to add it to our development of place value, groups of ten, and extra ones. I added an additional material of a tens frame to help students see the grouping of ten and extra ones. After we worked through all the steps (1-6) I added an additional step of scenarios where additional students were added to continue working with larger numbers with groupings of tens and extra ones. As well, students who needed to work with counting on from larger two digit numbers, this activity also helped to increase that knowledge.

Big Ideas: The same number can be shown in many different ways. 10 bundles of 10 can be combined to make a “hundred."
This lesson introduces the concept of "hundreds" and the various ways that one hundred can be made using groups of tens and ones. The task presents a basketball game in which the points are base ten values. The students are asked to think about and represent the different ways one could score 100 points. Understanding that there is no one "right" way to represent a number using base ten helps students have a solid foundation for later skills such as place value of 3 and 4 digit numbers, addition and subtraction with regrouping, and multiplication.
