2025 Summer Institutes
Early Numeracy, Addition and Subtraction for Grades K-2
Date: Monday, July 07 – Thursday, July 10
Time: 9:00 AM – 3:00 PM
Location: City College of New York – 160 Convent Avenue
Cost: $1200 per person
This session explores the development of numeracy in the early grades. The work will focus on the role of models and contexts for the development of number sense, including the use of both investigations and mini-lessons (number strings). We will use models such as the math rack, the t-chart and the number line as tools in developing important concepts such as place value, as well as the operations of addition and subtraction. The institutes will draw connections to the Illustrative Mathematics curriculum and will support teachers in seeing how these ideas unfold in IM.
Multiplication and Division for Grades 3-5
Date: Monday, July 14 – Thursday, July 17
Time: 9:00 AM – 3:00 PM
Location: City College of New York – 160 Convent Avenue
Cost: $1200 per person
This session will explore the development of multiplication and division, through both investigations and guided number strings. We will explore the use of models such as arrays, number lines, and ratio tables. This institute will be useful both for classroom teachers, special education co-teachers, and those interested in intervention for multiplication and division. The institutes will draw connections to the Illustrative Mathematics curriculum, supporting teachers in implementing IM tasks while also focusing on students’ mathematical development.
Rational Number: Fractions, Decimals and Percents for Grades 4-7
Date: Monday, July 21 – Tuesday, July 22

What is the cost of the Institute and how can I pay?
The cost is stated above. However, schools with several teachers participating in one Institute are offered a discount. After your registration, your school will be contacted to discuss payment. If you are participating as an independent teacher (without a school affiliation) you will be contacted individually. We accept checks and money orders.
Can I earn CTLE-Credits for my participation?
Yes! Summer institute participants are eligible for CTLE credits. An additional processing fee ($50) applies for those participants who request these credits.
Will I earn a certificate of attendance?
We do provide a certificate of attendance for those who request it, or if your school requires it. Please request one on the first day of the institute. The certificate will specify the professional development hours you earned at the institute. In the event that you miss a day, your certificate will indicate the number of hours you were in attendance.
Is there homework?
Yes, but not too strenuous. You will be given reading and reflection assignments. We want you to make the most out of your participation.
