Abstract
The purpose of this research to describe the level validity of mathematics lesson plan by using the Contextual Teaching and Learning (CTL) Approach on Quadrangle Substance at Grade VII MTs Negeri 3 Siak which was valid test. The development model in this research used an R&D model with six stages were the researcher have modified depends on the needs and conditions with current situation now it’s covid-19 pandemic. These six stages arepotential and problems, data collection, product design, design validation, design revision and final product. The data collection technique used in this research was the validation of lesson plan, the kind of data collection instrument was the form of a validation sheet. While the data analysis technique used in the form of descriptive analysis by describing the validity of the lesson plan which was developed by the researcher. The results of this research, the RPP validation were 85.86% with very valid criteria. While the results of LKPD validation were 89.81% with very valid criteria. Based on the results of this research, it can be concluded that the development of mathematics lesson plan with a Contextual Teaching and Learning (CTL) approach on quadrangle substance at grade VII MTs Negeri 3 Siak has been suitable for the validity.

Summary
Teknik pengumpulan data yang digunakan dalam penelitian ini adalah teknik non tes, dengan instrumen pengumpulan data berupa lembar validasi yang dibuat oleh peneliti dan diberikan kepada validator untuk memvalidasi perangkat pembelajaran matematika berbasis pendekatan CTL yang dikembangkan dan disesuaikan dengan kebutuhan peneliti. Adapun Teknik analisis data yang digunakan berupa analisis deskriptif yang mendeskripsikan kevalidan perangkat pembelajaran yang dikembangkan oleh peneliti. Instrumen yang dihitung menggunakan skala Likert dan skala Guttman. Sedangkan skala guttman hanya digunakan untuk mendapatkan jawaban tegas pada beberapa indikator pada angket validasi, seperti mencantumkan judul materi pembelajaran dan mencantumkan petunjuk penggunaan LKPD. Menurut Sudaryono (2016) skala guttman adalah skala yang digunakan untuk menjawab yang bersifat jelas (tegas) dan konsisten misalnya, yakin-tidak yakin; ya–tidak; benar-salah; positifnegatif; pernah-belum pernah; setuju tidak setuju
